Product description "Erica Synths - Drum Modulator"
Drum Modulator consists of two LFOs that can be operated either free-running, synchronized to an external clock or channel 2 to channel 1. If an external clock is connected, the rate potentiometers serve as clock divider/multiplier. Eight waveforms are available per LFO, which can be selected manually and continuously. Both LFOs have two outputs each: a main output and a 90 degree phase shifted output. The first LFO also has a VCA with its own AD envelope to, you know, modulate the modulator.... All in all a very useful modulator for drums to aggressive stabs and thanks to the sync and rate inputs also for generative patches.
