Improving the Vocoder on the R3! (maybe Radias too)

Post by axxim »

Hi,
just got an idea how to improve the vocoder effect. Since one important fact is to have a good quality modulator (besides the carrier of course) here is a way to enhance the mic signal:
  • Starting from your favourite vocoder program, activate timbre 2 by setting Voice Mode to Layer
    Edit Timbre 2 setting Oscillator1's Wave to Audio In, Gain to 0 (or adjust) and Balance to 0 or left (mic input)
    Set Mixer to max for Oscillator1 , and 0 for Oscillator2 and Noise
    Set LPFilter (24 or 12 dB) Cutoff to max and Resonance to 0 (clean)
    Adjust Amp level to 100 or more.
    Set the vocoder's Modulator Select to Audio Source (as usual) and Audio Source to Timbre2
By doing this the mic signal is now routed thru Timbre2 to the vocoder. And what is the benefit of this?
We can now use timbre2's EFX to improve the mic signal i. e. inserting the compressor, pitch shifter, etc. and we can adjust the EFX EQ. This way we will have an entire EFX tuning for the mic signal before it reaches the vocoder. Even we can use all timbre2 parameters to adjust more.
To hear, experiment and adjust the mic signal and its effects, turn the vocoder off and press Shift+Timbre2. When finished set the vocoder on again and hear/adjust the results!

Now there is a drawback on this: Using timbre2 and layering it, will leave us only the half of polyphony. Here is another trick:
  • Once the vocoder is finished, set the Voice to split
    Set the split key to the upper C (i.e.C6 or other key which maybe you never will play)
    Set the Arpeggiator On, to Trigger and Timbre Assign to Timbre2
    Edit the arpeggiator settings to Latch, Range to 1, Last Step to 1 and Gate to Tie (max).
To use the vocoder, now press the split key you defined, to activate and let open timbre2. Now there will be 7 voices left for the carrier! But take care: if you play more than 7 voices, then timbre2 will be closed (no vocoder because no modulator=timbre2) and the only way to reopen it, is pressing the latch button Off and On and then pressing the split key again.
If you don't set the Arpeggiator then you can use the split key as a gate for the vocoder in which case you can use timbre2's EG2 (Amp) to smooth the gates attack and release if you want.

Enjoy

you should also set timbre 2 to mono mode, otherwise you'll get louder when you play more than one note. And also it'll save polyphony for timbre 1 so you can have 7 note poly rather than four.

You are right X-Trade. This way one gets rid of loosing the gate.

Thx!
