A synth with standard analog circuits for sound generation and processing, with digital storage of settings, ARP and sequences. AI to be incorporated in an app that provides inspiration and downloads to the computer. liberal use of MCUs to manage stuff, and some innovative controllers to control sounds.
AI Powered Analogue Synth
Optional AI song designer app (python based) to generate:
- Midi sequences (Tested OpenAI and its crap for this)
- Chord transitions
- Wavetable generator
- Complete stems
- Post edit analysis/feedback
- Song Lyrics generator
- Suggest vocals/create vocals
With download to synth hardware via wireless/USB.
This bit is a tad tenuous 'cos my experience in this area with current GPT/LLM not great-but this could be because I need to get better prompts engineered to improve performance. Technology: user screen parameter selection built on python (hosted in a cloud provider) with link to OpenAI or Claude API
Synthesizer Outboard specification
- Fully analogue channels from generation to output.
- Storage of up to 4000 preset configurations including inter unit connections and all Pots values/switch positions. Selectable via rotary knob and by category.
- 8 Analog voltage controlled Oscillators with Sin/Saw/Sq/Triangle output can be used in combination or to create up to 8 note chords or can be separated for keyboard range to produce different sounds
- 3 LFO with 4 different waveforms
- 3D accelerator input controller can be used like a theremin or control over effects in 3 dimensions
- 2 CV in controllers, 2 Gate inputs, Selector for destination
- Slider pot controller (joystick?)
- 2xADSR plain env generators, 3x Multi vector Envelope generators
- Dual MIDI in and out via midi port and USB to allow two (midi or full syntih) keyboards to be used on different channels.
- Poly aftertouch – configurable to evolve into new waves or effects (like VCF/resonate)
- Flexible 4 channel Sequencer with up to 192 steps. Storage of 250 x 192 step songs + storage of infinite amount on computer or SD card.
- Beat designer (capacitive touch) 16 matrix with assignable sounds from SD card and stored in sequencer.
- Arpeggiator controller with note key alignment. Usual up/down, etc. + user design ARP rhythm.
- Wavetable to VCO - can be loaded as MP3 from computer via USB or micro SD. With listen to feature to enable selection. Selectable by category then sound. Optional store synth output as a wave. This one I have no diagrams for so winging this it a bit!
- Analogue in
- Noise generator
- 2x 2 VCF 4 in total 2 for each channel
- 2x 2 VCA -can route 2 different sounds through separate VCA and then down stereo route
- mixer
EFX unit consisting of 2x of each of the following to allow full Stereo wide effect
- Compressor using LM371 or SSM2165 with gating
- Delay
- Phaser
- Distortion DOD 250 type using Diode & LM13700
- Chorus also using MN3207
- Reverb MN3207 or V3205D (4096)
- Active filter with gate
- PreAmp out with filter and tubes
- Output to 1/4 jack and USB
management:
- Storage of settings
- Clocking of all elements
- BPM controller and separate display
- Display of ADSR waveform generators (and Osc waveforms)
- Config link
- App control via PC (and mobile?) of config and sound library
- Central control system with colour LCD touch display
Keyboard:
- Still to investigate keyboard as they are costly-
- Perhaps use Midi that is dedicated but provided as a separate box
- 2x MIDI input ports allows two separate midi keyboard controllers
- a Roli Seaboard type device.
- may put together a capacitive touch 1 octave thingy.
- Keypad for rhythm generation
- Keypad for routing
