Midilooper is a performative loop station that operates on MIDI messages. In contrast to looping in the audio domain where a lot of musical information has already been merged, this approach provides musicians with more flexibility to morph their loops. This way midilooper is crossing the gap between looping and sequencing.
For this device, we developed two special input circuits. One is a control voltage input that can be reconfigured through software into an interface for a passive pedal switch. The other one is a standard compliant MIDI TRS input that can also be used as a modular level clock input.
The firmware was developed completely by us. Its core feature is a storage structure for MIDI information that allows fast read and write access, arbitrary track lengths and flexible distribution of storage capacity between tracks. Additionally, it can be serialized to non-volatile memory allowing for fast and seamless switching between banks.
