hello, est-il possible d'utiliser le DFAM sur une des entrées du Lyra 8 (https://somasynths.com/lyra-organismic-synthesizer/) sans griller des circuits? sachant que le DFAM délivre du +12V et le Lyra accepte entre 3V et 12V sur le CV DELAY. Merci!
spécificités du Lyra au niveau des entrées:
EXT IN: Input for an external audio source. The external signal mixes with Lyra's voices and is processed by the delay and the distortion. It turns Lyra into a cool FX processor and also makes it possible to play a synth or drum line together with Lyra's voices through the internal FX units. When TOTAL FB or SELF in the delay section are turned on, the external signal will influence resonance and warp the modulation loops, thereby affecting overall synth behaviour.
HOLD GATE: A dynamic input for controlling the HOLD function. An input voltage of +5 volt will fully open the VCA. The more the voltage is lowered, the more it will close the VCA. With the control voltage at 0, the voice levels will decay according to their individual envelopes. Use the HOLD knob to adjust the level for each of the two voice groups. When set to FAST, the synth will react faster to a decrease in control voltage.
CV DELAY: This input allows using control voltage to modulate the delay time. When a cable is plugged in, the SELF and LFO modes are automatically disabled and delay modulation comes from an external source, regardless of the delay switch positions. Set the modulation amount with the individual MOD knobs for each delay line. The input signal must have a positive value and a 3 to 12 volt amplitude. The relation of delay time to the control voltage is linear.
CV VOICES: This input is for using control voltage to control the pitch of voices. The CV input will control the voice pairs with LFO CV chosen as their modulation source. Plugging in a CV source cable in the CV VOICES input will cause the control voltage to replace the LFO and TOTAL FB signals (which are bypassed automatically). The amount of modulation is set by the MOD knob in a given voice section. This CV input doesn't offer the standard 1V/oct logarithmic function necessary for achieving a tuned musical scale. It's a modulating input, not a tone-precise VCO control that covers the entire frequency range. Nevertheless, a step sequencer can be used to build melodic lines by ear. Combined with the internal modulation, this will yield interesting results. You can also try connecting an audio source to this input, e.g. a drum machine or another synth.
