I'm looking for recommendations for a hardware synth module that I can control live with a MIDI controller. I do NOT want to go the "all software" route... I'm already drowning in software synths and midi controllers. I want an actual piece of hardware with vintage synth sounds. I'm looking for something like the E-MU Vintage Keys but maybe a little cheaper / less features. I'm really only interested in some simple monosynth sounds. Looking for something I can treat like a boat anchor.
