The Leploop consists of two VCOs; the first with selectable wave form, the second with FM (source: VCO1, EG1 or LFO). Ringmodulation is possible, too. In the mixer section you can route and mix the oscillators. Of all sections the VCOs have the most modulation possibilites, even inverted envelope 1 or external CVs.
Further sound sources are a noise generator and the Cassa, a heavy bass drum with hard distortion, nasty distortion and attack. An external audio input is available, too.
Modulation sources: two attack-decay envelopes, a LFO with three wave forms, a flexible sample & hold generator and the sequencer. These can be routed by switches to almost all sections.
The sequencer has four tracks, memory and adjustable sequence length, depending on the number of tracks.
The filter is a resonant 24dB lowpass with modulation of cutoff and resonance. The input can be noise, the oscillator mix, the cassa or the external signal.
VCA1 is modulated either by the LFO, the 1st envelope or the S&H. noise, VCO1 or VCO2 can be used as audio sources.
VCA2 is modulated by the 2nd envelope only and it's input can be the filtered signal or the first VCO.
The final mix of Cassa, the 1st and 2nd VCA and the filter is set in a separate section.
