Fuser is a very simple mixer which I designed with the following objectives in mind.
Decent number of inputs: Fuser provides six inputs.
Flexible: it can be used as dual 3 inputs mixer.
Compact: it is 8HP wide.
Ergonomic: the knobs leave enough room for the fingers and the cables are not on the way.
My main use cases for this mixer are:
Combining my drum sounds using the 6 inputs.
Combining multiple oscillators (3) on one channel and multiple modulation sources on the other.
This is the block diagram of Fuser.
You can get Fuser as a fully assembled module, full DIY kit or Panel+PCBs.
