Rcently acquired a TASCAM DP-32SD Portasound multitrack recorder. This is my entry level into digital recording. Zero digital recording experience. The goal is to record my personal music musings. My unapologetic, indulgence in sound recording. To record, I have basses/guitars/drum machine and a Alesis QX49 MIDI keyboard. Recording bass/guitar/drum is basically understood. What's missing is the MIDI keyboard into the Portasound recorder. I need education/information on the "connector" gear that's between the MIDI and the Portasound. I've used the MIDI keyboard with Apple Garage Band and really enjoyed the virtual instruments. Looking to do the same without a computer. What am I missing?
