Groove Synthesis 3rd Wave: Technical Overview
· re:union Radio editorial · 1 min read
Bob Coover of Groove Synthesis discusses the origins of the 3rd Wave, PPG signal processing, SSI-2140 filters, and future projects.
In an interview with Amazona, Bob Coover of Groove Synthesis provided insights into the design and technical features of the 3rd Wave synthesizers. The concept originated during his time as a DSP engineer at Sequential following an exchange with Dave Smith.
Synthesis and Analog Filters
The sound engine of the 3rd Wave reproduces the signal processing chain of the PPG Wave. In addition to wavetables, the instrument includes analog synthesis, FM synthesis, and sampling options. Groove Synthesis incorporates analog SSI-2140 filters equipped with temperature compensation and resonance compensation. Users can also import custom audio material directly into the unit to create wavetables.
Models and Sampling Features
The product range features different versions sharing an identical sound architecture:
- Large keyboard model and desktop module offering 24 voices and four parts.
- 8M model featuring eight voices and two parts.
The internal sampler provides 35 seconds of memory, loop functions with crossfades, and up to eight multisamples per part. The setup also includes an internal pattern-based sequencer. Control design follows the approach of dedicated per-function knobs. Alongside Coover, the team consists of Andrew Silverman, Ross Wilcox, Eric Papp, Dave Peck, and Jake Thomas, with Mark Wilcox contributing to earlier design stages. Furthermore, Groove Synthesis is developing new products based on a different approach.
