Sampling modular synth oscillators with E-MU E5000 & Sample Aid

"...or how to prove emu + ocd = rsi
Looping & truncating raw VCO waveforms with no attack, decay or filtering - previous video (https://www.youtube.com/watch?v=87TS2...) [video 2 in the playlist below] showed how to sample complete voices so no looping was reqd. These waveforms can be used for building new voices inside the E-MU or by routing them back through the modular. They were captured earlier using Sample-Aid to step through each note, so the repetitive Arm & Place button pushes are still needed, but this time no auto-truncation was used so all samples are 1 sec. long.

The example shows one of the 40 pulse-width variations (10%, 12%, 14%... 88%, 90%) taken from the pulse output. Each sample is looped & truncated to approx. 2000 samples using E-MU's auto-correlate function plus manual tweaking by ear & watching the graph. The waveforms are simple so the tweaks were fairly consistent until the lower octaves where the size had to be increased. The lower notes were also harder to judge by ear, but it was easy to spot incorrect loop points on the graph.

Sampling this way may seem overkill but it avoids all compromises... you just need patience :)
Easier options would be to only sample every few notes, and/or truncate them to a single wave cycle, but you'd need to experiment with each waveform first to avoid audible artefacts.

Background music was a quick lash-up just to show what the raw pulse waveforms sound like with no further processing apart from the E-MU voice defaults. The E-MU was set to multi mode, with a few pulse variations assigned to different channels, and driven by Sequetron."

ARP QUADRA analog synthesizer from the year 1979

demo of all four synth sections (analog strings and phase shifter, poly-synth, bass-synth, lead-synth)

The Quadra is a four-section synthesizer consisting of a bass-synth (monophonic), poly-synth (full polyphonic), lead-synth (duophonic), and Solina like analog strings (full polyphonic)

The synth has included a awesome phase shifter, dual portamento controls and fantastic arpeggiator."

"Playing around with Steve Reich's "Piano Phase" on a Make Noise/Expert Sleepers 3U, with a little help from a Korg NanoKontrol and Ableton Live.

Ableton details:

Nanokontrol channels 1-4 control the signal inputs (DPO A sine, DPO A saw, DPO B sine, DPO B final):
Fader: Input level
Top button: turns Beat Repeat on/off
Middle button (not used here): toggles Beat Repeat output mode (Mix/Insert/Gate)
Bottom button: Engages record/overdub on a Looper (via sends A, B, C, D)

Nanokontrol channels 5-8 control the returns (A, B, C, D, each containing a Looper effect):
Faders: Return level
Top button: activates/deactivates Looper
Middle button (not used here): pitches loop up
Bottom button (not used here): pitches loop down
