Specific informations for the use of synthv1 !

More general information can be found on the samplv1 manual here. (same modules except GEN)

Synthv1 is an old-school all-digital 4-oscillator subtractive polyphonic synthesizer with stereo fx.
It's available as a pure stand-alone JACK client with JACK-session, NSM (Non Session management) and both JACK MIDI and ALSA MIDI input support, and a LV2 instrument plug-in.

Each of the two synths of a synthv1 instance have their own pair of Digitally Controlled Oscillators (DCO1 & DCO2).
You can choose a waveshape and a width for each DCO and eventually sync one to the other (makes the duty-cycle of one slave to the other when they are detuned) or limit the band.

The next knobs allows you to :

• Balance : crossfade between the 2 oscillators ( 0:onlyDCO1 , 0.5:equal balance, 1:only DCO2)
• Detune : symmetrical offset between the 2 oscillators
• (de)-Phase : Phase difference between the 2 oscillators
• Ring-mod : analog-multiplier
• Octave : Together with DCOx Tuning and DCOx Detune this parameter determines the tuning of the oscillators.
• Tuning : A finer tuning offset (in semitones) applied to both oscillators.
• Glide : If the value of this parameter is larger than 0, the synth will glide between the frequencies of subsequent notes (portamento), with a speed determined by the parameter. A larger value corresponds to a slower speed.
• Envtime : This parameter scales the envelope durations. A larger value makes the envelope slower. Envelope stage durations (always between 0.0 and 1.0) are converted to milliseconds in the following way msec = duration * envtime * 10000
