I'm looking for a cheap synth module with some decent bass sounds and a HOLD function. I'm playing bass with my feet while I play guitar and I would really like to get a note to stick after I've tapped it with my foot rather than holding it down myself. I've been using an old farfisa pedal wired to a crappy Korg monosynth. Santa hauled a fatar pedeal board down the chimney so I'm looking for something I can use to make some noise.

Many thanks
