This is the sort of finished version of the MemoryMode standalone synth / controller. https://youtu.be/csdjZZ96Cog

This is a revision of this project which was completed a few years ago. The front panels had faded in the sunlight and I always wanted to add a felt strip and some filters for the LED displays. https://youtu.be/9kS_OuyHRQw?si=20OZr6gBG6eI-aLD

That's an old one now, I couldn't program very well back then. But it works so I'm not going to break it. Was expensive to use a Teensy 4.1 on that, I think it could probably be handled by an esp32 now.

Thanks, I've been a member for a while but rarely post.

Thanks for the support, much appreciated. It keeps me busy during these crazy times

Thanks, much appreciated, but now I want to rebuild my 61 rack with the same editor and chorus in.

Thanks, it would be nice to have professional panels made, but the panel is just glossy A3 paper with a matte laminate stuck together to span the front panel. Designed with Front Panel Designers.

It's the case and keyboard of a CME UF 70 classic with it's guts ripped out and repurposed.

I purchased some boards for an Akai AX-80 and tested them, they worked perfectly with my home made front panel, so I created a set of displays similar to the original in functionality but using 2" OLED displays and added illuminated buttons. Then I decided it needed an editor to unleash the...

After upgrading my Poly 61's with Tauntek motherboards they were crying out for an editor to exploit the new sonic capabilities. So I built this simple encoder based editor that can store upto 400 patches in memory and exchange them over sysex with the 61 and other editors. Then I thought it...

Thanks, I wanted the AX-80 type of display but with a higher resolution and a lot more parameters.

This design started out as a sort of clone of the old Crumar Bit 01 design, but I soon realized that it was quite lacking and I couldn't make a good sound engine from it, so after a second attempt at digital oscillators and these failing badly I went with a micro controlled dual analogue VCO...

This is a new synth that I've been working on for a few months, it uses the Teensy Audio Library for the oscillators, noise pitch envelopes and LFOs, this feeds a CS42448 board that gives me 8 analogue outputs, the rest is analogue, Shruthi style 4 LP filters, Electric Druid EnvGen8c envelopes...

I've been building this synth on and off for over a year, it was originally designed as an 8 voice version of the Crumar Bit 01 with the same bi-timbral capability. Unfortunately these voices of the Bit 01 sounded pretty awful to me, so I scrapped them in favor of AD9833 waveform chips driving...

I want one

Yes I use the PWM output at 4x the base frequency and then use a counter and resistor ladder to generate a sawtooth similar to how the Crumar Bit Series synths worked. Its a slightly different way to get a sawtooth than the integrator method used in the Juno series etc.

I was considering using the 80017A clones for my latest project, but went with AS3372E filter/VCA chips. It's a similar idea of a digital oscillator section driving analogue filters, mine looks a bit more complicated as I have created a multi pole filter from the AS3372E and added lots of...

Thanks for the update, still quite a lot missing, LFO sync, LFO Mode, F-In, F-out, Curv. Envelope curves, VCA Velocity. Osc Mod and Mod amount. I have an idea for an extensive controller with upto 8 OLED displays showing all parameters, but I see now that the MOD matrix has gine up from 36 to 40...

Very cool, I was holding offf on building a hardware controller until I could work out the Matrix modulation and be sure all parameters are accessible over MIDI, looks like it's nearly there now.

Really it's not a problem, I'm happy and I understand the space issue, but as I was breaking it out to all 3 MIDI ports and two mono sockets it was just easier.

I just don't like the stereo combined output, it means I need a stereo to two mono sockets adaptor which is just a pain in the arse.

Wow, thank you for that, second time I've been featured in Matrix synth, last time it was because they thought my original Oscar Clone was a prototype 30 odd years ago.

These are CME UF-70 keybeds with new base panels and sides, keep the back panel and add the wooden frame.

This is a small collection of some of the real synths and accessories I have built over the last 4 years. Details of most of the schematics and code can be found on my GitHub page http://github.com/craigyjp A Roland A110 clone Rack version of a VA polysynth with extras A rack version of the...

Thanks, but I wish I'd finished the MemoryMode now.

Yeah, but it's a desktop and not going anywhere so weight is not an issues and that stereo output socket really bothered me.

Yes, compared to the originals a controller + pc is very simple.

A teensy 4.1. It sits on a daughterboard under the main controller front panel, it uses USBhost mode to read the USB keyboard and sends commands over DIN MIDI to the PC which has it's own MIDI interface.

Hi, everything is made by hand on my A3 printer and laminator, just need to build myself up to make the MemoryMode case and panel. But this time I'm going to use 3mm signage board in stead of 2mm aluminium to see if its easier.

So when I was 16 (around 45 years ago) I used to dream of the Arp Quadra. A friend of mine who wasn't a keyboard player, but just wealthy bought one and it was sat in his front room doing nothing unless I could call around after school and have a play on this great synth. Now I know I could...

Hi gang, built my Jeannie about 6 months ago but never really got to use it as it was just the PCB's. I've now created a custom front panel to allow me to use my square push buttons and a wooden case with individual L&R outputs and individual MIDI out and thru sockets.
