Nick,
the ABS module is a full rectifier, i.e. it doubles the frequency of the already existing waveform. If I feed it a triangular waveform, it will probably output a triangular waveform with twice the frequency. Plus it will be offset…. Can you think of a method of deriving a triangular waveform out of a saw, or vice versa? Maybe a slew limiter with adjustable rise and fall times can give turn a tri to a saw but I don't see any module that might do this.
The peak LFO is the 3rd value for the waveforms in modules such as LFO and LFO2.
