Matt Jones's Talking Neutron -- modified by LogicalPhallusy

Formant Voice S&H sample and hold filter voice robot

Changes:
1. Simply patched the S&H output into OD instead of VCA to provide access
to the overdrive, overall tone control, and delay circuits.
2. Skipped ATT2 because it's not needed, in order to free up an ATT.
3. Use bandpass instead of lowpass and square/pulse waves for a more dramatic effect.

TODO: Patch in some kind of small inverted keytracking on OSC2 to extend the useable range of the patch across the keyboard without having to manually tweak OSC2, which wants to be turned up when lower notes are played to keep a listenable sound.

(note: something strange is going on with the circuitry and I'm not sure if it's just my device or all neutrons, but for some reason this patch does not work if you try to use ATT2 instead of ATT1. If it doees, it sounds totally different and actually changes the sound of the output when not fully patched as soon as you plug a cable into ATT2 out. You dont even have to finish patching ATT2 out, merely plugging a patch cable in on one side and leaving the other end unplugged changes the sound. Very strange.)

Original: (Listen to audio preview for end result) Turn off osc shape blend mode. With the second osc set to full freq range, we can use it to clock the sample and hold at fast, audible rates (note: the osc first has to be attenuated as the full signal is too much for the sample and hold clock). The filtered 1st osc (with VCA bias open for uninterrupted audio signal) can then be sent to the sample and hold input and the resulting effected audio from sample and hold out sent to the VCA. Once patched up, use the Filter Freq to make vowel sounds. You might need to adjust the osc2 tune and/or filter freq to the correct range if the results aren't as expected at first. But if you follow the patch sheet it shouldn't be far off. The second option is to close the VCA bias, key track the filer freq, and use the gated envelopes (both 1 and 2 with env depth set to a little as shown) and play notes. You'll have to adjust the filter to the correct freq get the desired results (filter freq pot to about 10 o'clock). Try modulating the filter freq with some fairly quickish LFO for a vibrato effect.
