ProTip: Interesting Harmonic Distortion on the V-synth

If you want to emulate another piece of gear's harmonics, you can attempt to do so with the V-synth. With an FFT program, (I recommend SigScope) you can determine the harmonics of the amplifier distortion MFX on the V-synth.

1. Select a sine wave.
2. Play the note that closely relates to a FFT graph you are emulating. (In my case a 1k sine wave)
3. Use the Guitar Amp Master Fx and scroll through different settings to see the output.
4. Find someone else's FFT test graph for whatever piece of gear you are emulating.
5. Adjust the Gain & EQ to match the graphs. The harmonics are the lines after the first large spike. The spacing and height of each determines the change. You can just guess or do the best you can. You might not be able to match it at all, or you might find a new sound you like.

With the V-synth you must use really low gain both on the OSC and the MFC volume. If you hear the sinewave overdriving, you are a little too loud.

I was able to match Neve 1073 channel strip with two Marshall amplifiers, one in the COSM, and one in the MFX. Both had low gain. I used a LPF on the first COSM slot to have a bit of roll-off. You can also introduce noise into the mix on the second OSC.

Basically, it is "british EQ" on the V-synth!Does it sound the same?  I'm not sure I even care, I'm just exploring the sound pallette everyday with this keyboard. I'm sure I've done things the designers hadn't thought of.

So what can you do with all this? You could run audio through the input, or use the LPF for different synth sounds. SigScope pro can also check the waveform shapes if you want to explore more. If you have this set up, you will probably run out of slots for creating synth sounds, so maybe use a sample. If you have a JP-80 you could probably go wild, as it has more FX combinations. If you are going old-school, you could probably use a plate reverb.

So thats my tip for getting slightly different distortion textures! No matter what you do, you can never get things perfect, but its fun to try and explore the endless possibilities.
