I have a simple mixing section (Volume/Pan) for each of the 8 Tracks. And there is a TrackFx (Filter/Compressor/Delay-send/Reverb-send) and MasterFx (Compressor/Delay/Reverb)
You can route the audio out back into the input(with a cable, no internal routing). But you can also do automation per track. Currently only Volume/Pan, maybe also Fx Parameters in the future.
The hardest part of adding features is always, how do I make them accessible to keep the immediate feeling.
Here's a video from SuperBooth where I describe some of it's features. I added a lot of stuff since then ... and I'm not a sales dude so the interview was quite awkward ;)
Now I will be spending the day working out whether this is something I need in my studio ( the price puts it into a category where I really want to make sure it is something I will be using rather than buying it because I think its cool).
I also didn't want to compromise on Component quality. So I decided to order double shot Keycaps from the best Keycap Manufacturer in the US (solutionsinplastic.com). The case comes from a small Manufacturer in Poland. The PCB is produced by a Company in South Germany that also does Prototypes for Mercedes.
This all adds up. But I thought, if I can't compete on Price, I can try to compete on quality/repairability.
If I can prove product market fit, maybe I'll do a cheaper, less boutique version in the future.
One thing I used to really love with the early four and later eight tracks, was they had a mini mixing desk in them, and you could do things with them such as taking a line out and putting it into another channel, through some effects or playing the faders.
