Agreed, but even with the work / additional purchases IMO it still is an affordable and compact option, with future expansion to boot. Not for everyone, but it will be for some.

Yes, you could either insert into the channel you want delay / reverb or set up send and return so multiple channels can have FX applied. Does that help?

@@3dims so I’ve set it up with my interface 5/6 input and output looping from my interface to the microverb I’ve tried setting up the I/o plug in but having difficulties and not getting a signal through the microverb Trying everything and can’t set it up, unsure what’s up

@@ThEN003tr0ll if I were you i'd check each of the elements of the chain to see pin point what the issue issue is. For instance, is audio making it out of channels 5/6? Does audio come into 5/6 (without the Microverb in the loop)? Does the Microverb on it's own??? Do you have another effect (maybe a guitar pedal) you know works which you could use to prove the effects loop is working OK? Good luck getting this going - let us know how you get on.

That’s cool. I went through the same thought process. As an out and about interface this little fella is hard to beat for the money.

Thanks. Glad you approve!

Sounds like a smart plan. I think it’s smart to build up the creative reserves for when you are riding the wave.

😂

Nice one Patrick! So chuffed it’s been a help.

Hey Alex, there are a lot of people on the offensive when it comes to the JT-4000 and I agree with what you are saying. The iPad Mini probably is more powerful than I give it credit for, but I do tend to err on the side of caution.

You’re welcome

Thanks my friend. Appreciate you stopping by and leaving a comment. Have a good one!

Hey Patrick, thanks for stopping by and so happy you are into the RPi video. I tried to run MiRack on the Pi, but there’s no midi modules so I had to resort to iPad.

Of course it’s an OLED! Thanks for the spot.

I stand corrected! I’m relatively new to the MicroVerb 4, so happy to be wrong on this front.

Thanks. I’m still getting my head around the synth, so this is very handy to know.

I would suggest having a look at the RPi 2 power supply. I find that different USB plugs are better at isolating electrical interference than others. What are you using?

@@3dims I use a Samsung Phone power supply.

@@evertmeurs can you try another power supply? Maybe a USB power bank if you have one? That could help you isolate what's generating the noise.

@@3dims I now have a different problem. When I turn on my raspberry pi and my jt4000 is also connected, my jt4000 starting to play random sounds. When I try to play on my midi keyboard no midi connection and the jt4000 keeps making random sounds. Is my raspberry pi broken or something?

That’s a bit odd. My suggestion would be to try a fresh install of the OS. Could be a spot of corruption on the SD card which is creating some weird effects. Let us know how you get on…

Thanks for stopping by and sharing your thoughts. The Raspberry Pis are wonderful little (affordable) devices which have so much scope - I’m still just scratching the surface, but hope to go deeper.

The suggestion that the Holtek HT16... chip is an LCD driver... well yeah there is a 1621 but that would be weird, given it's the wrong kind of driver, it's a segment LCD driver, not a text/graphics one. I'd like to suggest that this is instead the HT16K33, a keypad scanner and LED driver with i2c. This way they can use a cheaper low pin count microcontroller (processor) IC, and then multiplex the i2c EEPROM, the i2c SSD1306 display, and all the LEDs (those in the push button switches) and the switches themselves plus possibly a rotary push encoder all on a single i2c bus.

Thanks for your input, it’s really fascinating to see what others know and can unpick from just a video. My knowledge is limited but is growing through useful contributions like this one. Thanks again.

Thanks for the correction. Every day is a school day. Cheers!

@@3dims I come from friends of Woody's Piano Shack, i'm their resident electrical engineer basically. They were looking at your vid. Found those guys when i ran into Floyd Steinberg's somewhat painful attempt to repair an Alesis Micron a few years ago. We ended up fixing it successfully.

@@SianaGearz that's so cool and really happy to have you most excellent input.

Thanks pal. Appreciate the comment.

No worries. I’ve been experimenting with the Pi to use more of its power, so expect to see this original idea expanded upon.

Pi Zero should work fine, its such a tiny amount of computation to route the MIDI data compared to what the Pi Zero is capable of. You are correct about the powered hub I'm sure too

Thanks for stopping by and letting us know your thoughts.

Thanks for sharing. It’s a bit difficult to know for sure, but I think you probably are right.

Thanks for your thoughts. I suspect Behringer had their reasons. It’s certainly proven to be a talking point.

Thanks, and totally agree some circuit bending would be ace. The tiny surface mounted soldering means that’s beyond my basic skills in this department, but perhaps someone will take up the challenge. As a bargain intro to hardware synths I think you’ve chosen well, I’m still discovering more about the JT-4000 Micro, so will share what I can when new, cool things occur to me.

@@3dims absolutely I don't really even know what's possible, but I've seen people modify all sorts of devices, but I haven't got a clue myself. haha

Thanks pal. Yeah, its certainly not a standalone device. The keyboard isn’t what I’d call playable - but useful to check the thing works!

Yeah, I’ve heard this was a thing. Apparently some other grooveboxes work in a similar way. Thanks for stopping by.

@@3dims Also did it with the Pro VS Mini too lol but yeah it works great

Thanks for stopping by

SSH is a way of remotely sending commands to the Raspberry Pi without having a screen and keyboard plugged into the Pi. Sounds more complex than it is.

@@3dims Thank you!

Beats me!

Thanks for the info. Really helpful insight. Cheers!

Why? If it's a classic analogue filter, then the pots specifically wouldn't be connected to the processor at all, the signal or opamp feedback just runs directly through the pots. Trying to make the filter processor controlled introduces a bunch of complexity not really desired in a toy-like synth, since you basically end up needing at least a shitty analogue multiplier plus more effective DAC channels, you can of course use the microcontroller outputs but end up needing to condition that signal, and you're quite space constrained in a device like that. At that point i'd be tempted to just completely get rid of the analogue filter and just implement a digital one, there is a DSP and FPU in the microcontroller.

@@SianaGearz are the filter settings programmable, and/or modulatable by the processor-controlled envelopes, LFO, or key tracking?

@@infindebula Good call. There IS a connection to the microcontroller that i missed, the filter knobs are also used to adjust settings. They also appear to be single track potentiometers. The cutoff and resonance are indeed completely automated, they have MIDI direct control, and LFO and envelope generator drive the cutoff frequency. So you're completely correct in your original assessment.

@@SianaGearz I’ll even go a step further… people bitch and moan when they see modern clones of analog monosynths - they say “why didn’t you make it programmable?” or “why didn’t you make the knobs respond to MIDI?” There is an inherent disadvantage to doing that, which we’ve just touched on. It makes every panel control subject to the resolution and latency introduced by the digital circuitry. Then some would counter “well you won’t hear stepping with 16-bit values” which is theoretically true, but the inherent noise in the whole system generally negates resolutions better than about 10 bits. Unless of course you attempt to dIgitally de-noise, which adds latency. For me, there is an unquantifiable connection between the player and synth when the analog controls (and keyboard) are actually in-circuit. Digital controls open up a whole new level of versatility at the cost of … well as I said it’s unquantifiable, but there is something there!

Superb. Thanks for chipping in.

The single filter doesn't bother me TBH. Also, I'm not sure where Behringer would fit another 2 analogue filters into this miniscule box.

@@3dims Apart from the JT-4000 and Pro VS mini, which are without a doubt toys, all of my hardware synths are fully polyphonic. My only paraphonic synth is my Waldorf Pulse 2 and even that clearly states that it's a Monophonic synth. Behringer could easily have made the JT-4000 large enough for four analog filters. Look at the Pro 800 eight voice synth with eight analog filters for £300 and not a large synth. That works out to £37.50 per analog voice and analog filter so £150 for a completly analog and fully polyphonic version of the JT-4000. I would've bought a Pro 800 if I didn't already own a DSI tetra and a Rev2 16 voice.

@@straighttalk2069I have a Pro 800 and it’s a class synth, but totally different form factor to the JT-4000.

Quit moaning and let us enjoy them 😂 ​@@straighttalk2069

@@straighttalk2069 The Korg Poly-800 also had only one filter, and it became a top seller not only for his price point. No one would call that a "toy", just because it was only paraphonic.

Good spot… I’ve just opened up the JT-4000 and tucked the ribbon cable away from the moving pot. I suspect the ribbon cable got free-d up with me messing…

Cool plan. I’m guessing you’d have them on the same midi channel and either make a massive sound or pan left / right.

@@3dims the jp4000s gives me a simular synth like a multitimbral Synthesizer. I have 3 Single outputs, and 4 Voices each. Most time I use 1 for left hand and 1 or 2 for my right Hand. I case of 2 I Pan hard right and left or sometimes I am just stacking the sounds without planning. The Jp4000 has a very good sound, from poor little whispering to fat supersaw, everything is possible. All in all, the sum of the bill for 3x synths was less than 150 bucks 🤣🤣🤣that's worth the fun!

@@texacomann I like it! It is a load of synth action for very little cost...

Nice one!

Works on the KORG Nu:Tekt too

@@kenfuller9907 which is perfect as you only need one power supply.

Anytime my friend.

No worries. I’ve got a Pi 3B now as a dedicated USB midi USB host. It works a treat.

Nice one. Glad to hear you are seeing past the diminutive size and getting some interesting stuff out of yours. I have been considering getting a 2nd, but will hold off for the time being as I’ve still got more exploring to do.

Thanks for stopping by Floyd. Love your channel and find it a source of so much useful stuff.

I thought so. There are other options but this seemed to be more budget friendly.

Absolutely. Awesome you can make cool tunes with a toy these days!

So were the 303 and 606. Cheap plastic boxes. Doesn’t mean they aren’t useful and can’t sound good…

100% agree. I drew the same 303 comparison in a previous comment (on another video). I aslo got to thinking about how LFO use a Speak & Spell on their eponymous track, so we are in good company :)

Anyone who thinks that way doesn't deserve one anyway.

@@SpeccyMan 😂😂😂

It’s the 32bit flavour of Raspbian.

Thanks dude!

I’m sure you are right, but I can only use what I have.

Fair enough. If there wasn’t an analogue filter then I’d be right there with you. For me, the filter makes the JT-4000 good VFM.

Nice one. Thanks for the heads up…. BTW the manual is split in a weird way, so there is more detail in it, however not the easiest to read TBH.

To save a sound on the Behringer Pro-800, you can copy and paste a preset: Go to Preset Hold down Preset Press 5 to copy Change banks Hold down Preset again Press 6 to paste Press 6 again to confirm

@@TheShaktube Thank You Very Much. Great Solution!

Ah cool. I also hear MPC One works without a MIDI Host. Unfortunately I have neither of these. Thanks for letting us know.

I tried the KeyStep and it will not work

That’s refreshing to hear… I’ve moved between Dawless and hybrid over the years, but if you read some of the comments on my last video you’d think not having midi in was the living end. There may be some truth in leaving stuff out, either to encourage upsell or discussion.

Thanks for adding these points

The other option I will try out in the future is using AUM on the iPad Pro I have. This should work DAWLESS, but I felt the Pi was one of the more cost effective options, so decided to plump for a video show casing this in the first instance.

No input for processing I’m afraid. Output is headphones…. Gotta remember the price tag.
