The reason for that is that most of us have approached the C4 with the need for synth bass sounds and recreating or replacing other pedals further limiting it's potential in our bands or recordings. Placing those limitations with it rather than simply exploring the limitless possibilities that the brilliant designers of the C4 Synth Bob, Roger and Jessie probably envisioned when they set out to put a 4 voice Eurorack synthesizer in a pedal that we can trigger with an audio input without the need for a MIDI signal.
For example keyboard players are still exploring 50+ year old synthesizers that are seriously limited in capabilities in comparison and finding new sounds and possibilities and spending huge amounts of $ to buy or lease vintage machines or pale reproductions.
Luckily I have had time to explore the possibilities of the C4 and have a little bit of experience in Electronic Music and am working on recordings I hope to soon share using the C4 as the prime sound source. I hope others are doing the same.
