"Double Six is a 6-operator FM synth with 32 DX7 algorithms and 16 4-operator algorithms.
* 6-operator FM synth with 32 DX7 algorithms and 16 4-operator algorithms.
* Every operator has its own envelope. You can choose between 1 and 8 stages and set the sustain point from 1 to 7 or off.
* Every operator has a clipper,overdrive,lowpass filter,and a distortion.
*
* 2 octave sequencers with Destinations operator 1 to 6.
*
* 4 envelopes with retrigger mode on BPM rates.
*
3 LFOs with 19 different waveforms with 16 different BPM rates and free rate(manual) mode.
Destinations of the LFOs are pitch operator 1 to 6,phase monulation 1 to 6 and cutoff
* The LFOs can start free (anypoint of the lfo waveform) gated starts when you hit a key or first (starts when you hit play in the sequencer).
* A ocatve pitch
* 14 different curves for the envelopes.All envelopes have a time knob.You can switch between the envelope and volume.
*
* The operators can be disabled, fixed or pitched and have a octave range from -6 to 3, fine-tune and pulse width.
* 11 different waveforms for the operators.
* The filter has the same envelope and there are 10 different filters types low-pass 12db,low-pass 24db,low-pass db32, hi-pass,band-pass,CK low pass,CK Band pass,CK hi pass,CK notch,CK,peak.
* Volume envelope.
* EZ preset: This allows you make new sounds fast. You can reset all fine-tunes with the hit of a button or change all waveforms, set all the octaves the same and the times of the envelopes.
* Phase modulation depth control and a feedback control
* Volume envelope.
* Note sequencer
* Build in effects are Chorus, stereo delay, gater,clipper,ovedrive,distortion and phaser effects.
* Velocity controls
Voice/poly controll"

"38911 Bytes v3.0 is a one oscillator synth
It`s a synthesizer based on Commodore 64 software but it can do a lot more
It has 1 oscillator synth with 4 waveforms (Saw, Triangle, Pulse,pitched Noise) ringmodulation waveforms (Saw, Triangle,Pluse). PulseWidth Octaves from -3 to 4.
1 ringmodulation oscillator with 3 waveforms (saw,triangle,pulse) PulseWidth,octaves range -3 to 4 and notes C to B
3 LFOs with 19 waveforms,16 different BPM rates and FREE rate (manual)
They have a low/hi depth option and destinations are pitch oscillator, pw and cutoff
The LFOs can start when hitting a key (GATE) start when you hit play in your sequencer (FIRST) and start at any point (FREE)
4x16 step sequencers:
With 11 BPM rates and FREE rate mode (manual) in FREE mode all sequencers have the same rate.
1 waveform sequencer you can select the following waveforms (saw, triangle, pulse,pitched noise,RM Triangle,RM saw,RM Pulse)
1 octave sequencer range from -3 to 4
1 Octave and notes sequencer notes form C toB and octave range -3 to 4
