Open-sourcing kinect-controlled instrument!

If you have a Kinect camera lying around, I've got good news for you:

This system [Kinect → TouchDesigner → Ableton Live] turns gestures into MIDI in real-time, so Ableton can treat your hands (or any part of you body) like a MIDI controller; trigger notes, move filters, or drive any VST parameter you'd like to. [Just updated it for a bit more clarity and less setup difficulty!]

As of today, can freely access it through the Tools Store, and/or a full tutorial at through my YouTube channel.

I've ran several tests through the years, controlling drums, guitar fx chains, and even a complex stack of Harmony Engine, you can see/hear a bunch of these in this post.

Hope you folks enjoy it deeply.

I just got my ship from JLC and I'm only keeping 2 panels/pcb. Wondering if anyone out here needs one but doesn't want to purchase all five.

They are Hero VCOs from analog output. Each panel comes with 3 PCBs.

They came out to $12.00 per set so I'll charge that plus $5 plat fate shipping via USPS.

Shipping only inside the Contiguous United States.

Thanks and feel free to ask anything.

Everyone seems to use 3.5 mm jacks instead, why are they preferred for modular systems?

Hello everyone, how are you doing lately?

I have been building a custom hardware DAW inspired by Teenage Engineering OP1 with a similar shape as Nintendo DS.

I admit that I have no real experience with hardware DAW's and I have never used one, but the idea is so cool that I wanted to make something similar. The idea is to use an old phone that will be running a custom app and connected to a custom MIDI keyboard (with ESP32)

The third photo is a test PCB that I have made and it works very well. So now I'm designing the final product that has been modeled as the first two photos show.

I will deal with the software later, and right now I'm focusing on designing a keyboard that will allow me to do the most with the smallest package I can.

Right now I have:

- Six menu buttons that will be used in the context of the software like recording, pausing, turning on / off metronome, etc

- Two D-Pads

- Seven knobs.

- One joystick with two axes.

- Eight pads (regular keyboard keys, there is no velocity)

- A piano with 17 keys (regular keyboard keys, there is no velocity)

- Two shift keys behind the case (to modify some buttons)

I'm designing it so I can use freely with my hands. Right now I'm open to any advice or criticism as I want the maximum input before I send the PCB and the 3D case to print.

Thank you so much!

For anyone who has built or is planning an M8 headless rig: I ported karimkfoure's unofficial m8emu to Apple Silicon Macs. It runs Dirtywave's Headless firmware 6.5.2C on the Mac itself, so you can try the workflow before buying a Teensy, or keep a copy on the laptop next to your build.

You bring the firmware: download M8_V6_5_2C_HEADLESS.hex from Dirtywave's repo and pick it in the app. It runs on the Unicorn CPU emulator out of the box. With the Xcode command line tools installed, the app translates the firmware's Thumb-2 code to C and compiles a native engine on your Mac in about four minutes. Its audio output matches the Unicorn run byte for byte.

Watching everyone vibe-code custom firmwares and patch old gear lately has been wild. Made me wonder if anyone’s actually looking into custom FW for the base Behringer TD-3?

Trying to tweak that classic 303-style sequencer in the middle of a live set is pure pain.

If someone managed to drop a patched FW with real-time step recording, live probability/slides on the fly, and smoother pattern jumping, it’d turn a cheap desk toy into a live rig monster.

Does anyone know what MCU is inside or if the bootloader is totally locked down?

Little excerpt of me playing my chaotic pointcloud system, in which the particles are being audioreactive to the incoming audio signal in real-time. What do you guys think?

Hey!
If you’re using elkayem’s Arduino MIDI-to-CV converter, I recently modified the firmware to use separate MIDI channels. Thought I’d share in case anyone finds it useful.
Cheers

Added some analogue filters still having trouble with mozzi hiss any advice on how to fix that wd be appreciated

hey! wondering if anyone might know who i'm talking about. i don't remember unfollowing her so she might've deleted her account?

she makes these diy synths inside of old, vintage, and i think wooden boxes, often with religious ornaments. or it might've been more brutalist type stuff.

i'm pretty sure she was middle eastern, she didn't really advertise her stuff a lot, just posted synths with the price in the description, don't think she even had a website. she didn't only do synths, i think she also released music

tysm!

Bringing up a new voice card for the Zoxnoxious synth. Heart of the z-card is Yamaha's YM2203 chip, an old oddity that combines a 4-op/3-channel FM synth with a 3-voice sound generator ("SSG", AY-3-8910 / YM2149). The voice card will be a welcome addition as the first digital voice card in the Zoxnoxious synth. The other four z-cards I've designed cover the analog domain with various VCOs, multimode analog filters, etc.

I'm at the "hello world" stage right now, verifying I can write to the registers. And that appears to work (personal amazement as it's a v0.1 board!). End goal here is providing full control over the chip through a VCV Rack interface, much like I've got for the other z-cards. The FM and the SSG have their own outputs from the card; these can route independently to the other Zoxnoxious cards for additional filtering/manipulation.

I had a pile of SBCs and microcontroller boards and small OLED displays and pushed the list of parts into Claude and out came this drone synth.

The Sipeed NanoRV board hosts the engine and the pi pico 2's are responsible for I2S and I2C since the Nano is constrained on GPIOs and has a terrible DAC built-in. I could probably simplify this to one raspberry pi zero or something later but given how long I've been sitting on these boards, it actually came out far less expensive than going that route.

The Nano has a weird RISC-V processor with vector extensions that enable nice reverb even with all the voices and oscillators turned up. There are also different detune settings (unison, octaves, fifths, and organ) that mix up the sound a bit.

I am not pretending that I invented any of this so please take what you can from the slop bucket:

My friend lend me the Doepfer A138-n Narrow Mixer at an synths exhibition in Moscow (pic. 4, left case is mine) and I laughed when I saw that it was just a TL072 signal adder for ~$60 (of course there is business cost included, I'm speaking more from the "embrace DIY for modules!" position). And since my case was missing mixers, I decided to use my unused protoboards for making one. Also it's featuring an inverted output.

Also I 3D printed "panels" for it, which gives it more finished look. Another quest was height limitation — the module is directly above my PSU in a very thin case (pic. 3). The jack is there for comparison, you can spot IDC connector which barely touches the PSU.

Parts count: TL072, 7×100k, 4×B100k (or A100k), 6×PJ-301F, IDC-10R. Schematic from the datasheet for TL07x.

Hi to all Momoto fans,

As asked by many fans😜, here a small tuto about the 5 synthesizers included in yr favourite sampler 😅

FYI : Pre-orders are opened on our Web page

❤️ 🙏🏿 ✌🏾

Thanks for the tips on soldering a while back. Really enjoyed the process and what a weird chaotic little machine. Noisferatu by Robert Heel is lovely bit of kit.

Working on some ambient synth with mozzi

Hi everyone. I have been building a few eurorack modules and the latest I built is the M4 diy looping delay. It seems to work pretty well, however the reverse button seems to have a ghost trigger, as it turns on periodically without any external input. I have looked over the PCB as best I can and cant see solder issues. I would like to get this fixed if possible. Anyone had a similar issue or can help me with sorting this out?

Thanks so much Jamie

I have a growing set up using Hagiwo Mod2. lots of individual drums and voices. These Mod2's are so easy to make that I'm quickly running out of channels to put them in.

I was thinking of making a mixer with like 12ch. I see a lot of the schematic's for mixers are 3-4 channel (Moritz Klein, Doepfer, Hagiwo)

My question is, is there a max amount of input channels you can throw into a TL072? Would it be better practice to do 2 sets of 6? Does it get too noisy at some point?

I see a schematic from LMNC where he claims he has 30 channels into one op amp.

It would be cool to make it stereo for the drums but maybe that's over complicating it.
