Tiptop Audio / ART Octopass

OCTOPASS is an 8-voice professional 24dB/Oct low-pass filter module based on the 2044 filter found on traditional and iconic synthesizers.

All eight filters are fully analog, with linear gain compensation for resonance and voice-to-voice error correction. Polyphonic patching is available for audio signal input and output as well as filter cutoff, and an FM Level CV input via a 3.5 mm mono jack can be used to modulate all eight cutoff CVs input through the POLYTIP jack. The module contains eight filters and is specially designed for power efficiency.
