OktaDie — Organismic Touch Synth on iPad | Drone Demo, No Talking

video upload by Diego Capoccitti

Follow-up to this post.

"OktaDie is an 'organismic' synthesizer for iPad: eight touch-sensitive voices, a cross-modulation matrix, a dual modulated delay and an overdrive — with no keyboard, no scale and no quantisation anywhere in the signal path. No talking in this video: just hands on the glass. Everything you hear is OktaDie running standalone on iPad (AUv3 plugin versions included), played entirely on the eight pads — no MIDI keyboard, no sequencer, no external processing.

🎛️ ABOUT THE INSTRUMENT
The eight generators are closer to a vintage electric organ than to a VCO. TUNE moves each voice continuously across a huge untempered range, SHARP morphs the waveform from triangle to square, and the envelope shapes pitch and waveform as it moves instead of just opening a VCA after it. Voices work in four pairs and two groups, each pair picking its own modulation source — another pair, the Hyper LFO, or the instrument's own output. TOTAL FB feeds the post-distortion signal back in and turns the whole machine, delay and drive included, into one giant FM structure. Noise, bleed and drift are features here, not defects: it never produces exactly the same sound twice.

👆 PLAYED BY TOUCH
Eight multitouch pads replace the keyboard. Play with several fingers at once, slide sideways to glide from one pad to the next, press harder to open the envelope further — OktaDie reads the contact area of your fingertip, and Apple Pencil pressure where available.

📱 iOS VERSION (iPhone & iPad)
Standalone app + two AUv3 extensions: OktaDie as an instrument and OktaDie FX to run your own audio through the delay, drive and feedback loop. Works in AUM, GarageBand, Cubasis, Drambo and Logic for iPad.

💻 DESKTOP VERSION (Mac & Windows)
Available in AU, VST3 and AAX formats for all major DAWs. Presets are shared with the iOS version.

A single HTML file that turns any Chrome or Edge browser into a full editor and librarian for the Yamaha TX802. Connect over MIDI and take control of the whole machine.

Voice editing — Every FM parameter on screen: all six operators with knobs for envelopes, levels, scaling and frequency, the LFO, pitch envelope, and the full 32-algorithm chart drawn exactly as Yamaha's. Plus the DX7II-era extras — poly mode, portamento, pitch-bend step and the complete controller matrix. Edit live and hear every change as you turn a knob.

Performance editing — Set up all eight tone generators in one grid: voice, MIDI channel, output, detune, note limits, tuning and more. Factory Preset A and B voices show by name, and linked tone generators resolve just like the module's own display.

Librarian — Read, save and reload all 64 voices and all 64 performances as standard .syx files. Double-click any voice or performance to load and play it instantly. Every write to the module is verified and read back, with a clear warning if memory protect blocks it.

Also — Full SysEx monitor, drag-and-drop file loading, remembered MIDI ports, and built-in help on every control.

*fractional scaling and micro tuning is not implemented in this editor.
*this is NOT fully compatible with the DX7II except for some voice editing

Made as a personal tool. Shared as is. I offer no support for this."

EMS 256 Sequencer Repair Part 3

video upload by Really Nice Audio

"I socketed all the IC's and tested what I could. Found almost 20 faulty IC's through this process. Thanks to PCBWay for making my extender boards. If my design is correct I will share the design on PCBWay so all the thousands of people that need to fix their 256's can order their own.

This 256 is part of the Pete Townshend Synth collection housed at the University Of West London. https://www.uwl.ac.uk/study/study-fac..."
