about

Demo 01:

This demo was intended to demonstrate how the Manhattan Analog VCA responds to a variety of envelope shapes, along with some Amplitude Modulation (AM).

Patch Details

1. Braids was used as the sound source.
2. The 4MS Pingable Envelope Generator was set up to produce various chaotic, random envelopes.
3. The Doepfer a149-1 was used to modulate the DIVISION of the left envelope, and then the EOR output was sent to the right PEG envelope to ping it - but this envelope was set to half the DIVISION of the left one - this creates an effect whereby one envelope receives its modulation first, juddering away, and then the second one follows a short time afterwards once the EOR pings get through to it.
4. The EOR output of the left envelope was also used to sync the start of Braids' waveform, via the TRIG input - giving the clicks more consistency.
5. The outputs of the two envelopes were sent into the two CV inputs of the Manhattan VCA, and brought in manually during the recording. The OFFSET on the VCA was also tweaked a little way in, filling out the sound.
6. The PEG's envelopes were set to Exponential and Logarithmic shapes respectively - as you will be able to hear in the recording, one is much "spikier" than the other.
7. Towards the end I drive the PEG up into audio rates, and some savage AM (Amplitude Modulation) of the VCA occurs.

Reverb added during mixdown. No EQ.
