FM Synth with hands-on control.

So I've decided to make another FM Synth mockup. This time not a clone. Behringer is free to use this for their convenience. I'm not a designer and this is not what I do for work. This is made on my own spare time, driven by my interest for FM synthesis. But also the urge to inspire a manufacturer to make something like this. There has never before been released an FM Synth with Control-per-function, and FM needs it more than anything.

This is based on the idea of making FM synthesis as approachable as possible. There are some limitations compared to a DX7, but there are some advantages as well. It's a different machine.

Voice structure:
Technology: FPGA-based, with oversampling at MHz-rates for minimum aliasing, and maximum sweetspot.
Polyphony: 64-128 voices.
Operators: 4 Operators per algorithm.
Algorithms: 5 algorithms per part. (20 Operators per part)
Parts: 5-part Multitimbral. (Performance mode is the only mode), (100 operators in a performance)

Algorithm:
All operators can be freely assigned to modulate each other in any combination.
All operators can be both modulators and carriers simultanously.
All operators has their own dedicated feedback knob.
Each of the five Algorithms are separate from eachother and their outputs are mixed together before the effects stage in the audio path.

Operators:
Oscillator:
Multiple waveforms suitable for FM.
Coarse: Multiplies the frequency through the harmonic series.
Fine: Linear frequency control suited for inharmonic sonic content.
Detune: Suited for making thicker sounds and movement.
Fixed Frequency: Removes keyboard tracking. Suitable for Enharmonics.
SYNC-OFF: Turns off phase-lock. Make random phase position each time you press a key.
Modulation: Velocity, Aftertouch and modwheel have dedicated controls for modulation depth.
Envelope: Standard ADSR dedicated to control amplitude over time.
LEVEL: Controls the maximum amplitude of the Operator.
Key-Follow: Allows the keyboard to control the amplitude.
OPERATOR SELECT: Select one or multiple operators to edit them. You can also copy Operator settings.

AUX - Envelopes:
Both envelopes are identical.
Standard ADSR.

MOD-Assign: Press and hold down, and turn any knob for mod depth for the corresponding parameter.
Or press once to select more destinations on the display.

LFO's:
Both LFO's are identical.
Wave: Select standard waveform for the LFO. Wave name is shown on the display when you change the value.
Speed: Change the speed of the LFO by value or musical divisions depending on the Sync setting.
Delay: Change the time it takes for the LFO mod depth to fade in.
MOD-Assign: Identical to the AUX-Envelope.

Keyboard:
To transpose the keyboard, use the OCT - and OCT + buttons.
Activate Chord Memory with the CHORD button.
Press the ARP button for ARP menu on the display.
Press the HOLD button to sustain the sound when you let go of the keys.

OPERATOR - OFF:
Turn off operators. Handy for programming, but also for live performance.

Display Menus:
The display area complements the rest of the synth by giving you additional info and settings.
Press the SETUP button to access common settings such as midi, audio routing etc.
Use the VALUE knob to change the value of the currently selected parameter.
Use the navigation buttons to navigate and change values on the display.

Effects:
Access each effects-processor menu by using the FX 1 and FX 2 buttons.
Both effects-processors are identical.

Better than Korg’s crappy UI

Re: FM Synth with hands-on control.

The one from Korg is 6-OP [like DX-7], this model above is only 4-OP so you wont be able to use DX-7 patches.

Yes It's a bit disapointing. There is a chance it's a prototype and could have more controls. But I doubt it.

Yeah it's meant to be a different take on FM from DX7.
