Synthi V - General questions

Do you have questions about the Synthi-V?
You will likely find an answer here:

Oscillators level and shape

The Synthi-V oscillators volume and shape can be adjusted independently.
Both the level and the shape have an influence on the modulation amount and the output volume.

/!\ When applied on the square wave (OSC2 and OSC3), the shape will shorten the pulse width.
When pushed under 2 and above 8, the waveform will become a DC and won't produce any sound.

Modulation Matrix

Synthi-V is a modular synthesiser, but not a semi modular synthesiser.
This means that from a blank preset, no sound will reach the synth output.
Consequently, when feeding audio in some of the Synthi-V modules, at the end, you will always need to feed the audio from the last module to the Output Channels 1 or 2.

Channel outputs volume

At the end of its audio path, Synthi-V is equipped with two output channels.
Both channel's volume and pan can be adjusted independently.
As the output channels are located at the end of the signal path, make sure their level is not at 0.

Note: Most of the Synthi-V modules have a dedicated level control. So each time you connect one to your signal path, make sure its level is not down to 0.

Audio feedback (also known as Larsen effect) is a phenomenon that occurs when a signal is reinjected from an audio output to its own audio input.

Depending of the environment properties, an accentuation / attenuation of specific frequencies is observed and often results in a drastic amplification of the output level.
If the reinjected signal is not attenuated, the effect grows until it reaches the limits of the output level (Saturation).

This phenomenon can create very interesting effects, hence its widespread usage since years in many music genres.
Nonetheless, when this effect is created accidentally, it can lead to a powerful blast that can damage your speakers, or even your own ears.
That's why we recommend to always work with a limiter on your master or track, so you can keep experimenting serenely.

See below a concrete example of a feedback loop setup:

Here, the output of the reverb is directly reinjected in its own input.
Consequently, as soon as the Reverb Dry/Wet and Level are raised up, any signal going through will create a feedback loop.

On Synth V the modulation matrix and two distinct parameters are controlling the keyboard and the sequencer effect.

Pitch Spread

Controls the tracking of the pitch for the Keyboard and Sequencer.
The default value is 5.50 (Semitones), lower values gives microtonal intervals.

Envelope Shaper

Determines if the envelope is retriggered by the keyboard, the sequencer, or even both.

Mod Matrix

Remember that the Synth-V is modular, and not semi-modular.
To control the oscillators pitch with the Keyboard and Sequencer, you will need to connect them together through the Mod Matrix.

The original Synthi AKS hardware features a unique envelope generator, composed of four parameters and two distinct output levels.
This envelope is at the same time a VCA and a voltage generator.
Controls the onset time of the triggered envelope, from instantaneous to over one second.
Sets the envelope output value held time after the trigger signal is released.
Determines how quickly the envelope fades away after the "On" time (Release)
Controls the self-retrigger time (Self-retriggered < 7 < Manual)
Sets the output level for the control voltage envelope being created by this module.
Envelope Signal sets the output level of the audio signal being processed by the module.
Group assign has a double function.
First it lets you modulate any modulation amount on the matrix, but that's not all.
It also lets you create up to 4 macros (A, B, C, D), and modulate multiple modulation amounts at the same time.

Instead of using a standard pin, use a letter pin will assign the modulation to one of the groups. Then in the modulation matrix, modulate one of the groups, for example the A, will modulate all the Matrix A modulation amounts.
