There is no "reset". The light remaining constantly lit indicates circuit failure. There's a former TEAC/Tascam technician posting as Skywavebe on tapeheads.net who may be able to help you.
A MIDI controller is generally an electronic instrument that doesn't create its own sounds. It could be a keyboard, guitar, wind controller, drum pads, or whatever. You can use it to control the synths in other keyboards, rackmount modules, or VSTi synths on your computer.
The MG166C appears to be made for use with a DAW rather than a multitrack tape recorder. You could try connecting the group outputs to the recorder's inputs and bring the recorder's inputs back in through 4 unused channels. Be sure not to assign those 4 channels to a group, or you could get...
Something frightening to contemplate, I imagine. Let's focus on the OP's technical questions.
OP, there's going to be at least a 3-step process here.
First, record the song as MIDI data and save it to a file. Any DAW, such as Reaper, can do that. There are most likely a number of standalone...
You can record the audio straight from your keyboard onto an audio track in your DAW if you're just looking to capture a live performance. If you want to edit aspects of the performance in the DAW or take advantage of samples or VSTi instruments stored on your computer, MIDI is what enables you...
Ableton was the one I had the best experience with when I was tooling around with DAWs. It has a huge instrument and drum kit library in addition to the usual DAW functions. The Wurlitzer 200A emulator that came with it was the best I'd ever heard.
Did I ever send you that mixer, Henry? I don't have those Behries anymore. I left them on a shelf at my ex's house after I got my M-308. I have a little vintage TEAC/Tascam 4-channel desktop mixer I can spare if the kids still need one though.
Some engineers swear by spring reverbs for adding depth to an instrument or making it stand out. That usually involves EQing and/or gating the reverb, and has a different goal than the typical use of reverb, which is adding a sense of space. A couple of manufacturers made BBD analog reverb...
The thing about building a studio is, you can't miss any pieces if you don't know what the missing pieces do. Strictly speaking, all you need is a mixer, a recorder, and some mics to start. (That's a computer, audio interface, and DAW program to you digital folks.) You can add in other pieces as...
Program Change is a type of MIDI message (aka "event"), not a sequencer function. If there is a PC message in the track, you should see it in the list of messages on that track. The sequencer should provide a way to scroll through the messages. If there's not a PC message in the track, you'll...
Now that I think about it, you should be able to insert a PC message into the track or edit the number of a pre-recorded one in Event Edit Mode. Keep in mind that the Q-80 uses the zero-based MIDI PC numbering system, while a lot of (most?) synths start the voice numbers at one. So you may have...
