now do it with only default events and no named bricks(if you have any allready)
Its not possible without making the machine overly evented and massively bulky-- recording and playback would require a massive computer at least four times the size of the one inside this piano, and even then I don't think it would be possible because there would be no way to tell what was toggled or not without making an additional brick that toggles whats toggled-- it gets messy and impractical without VCE.
The named brick thing would be useful if you wanted more than one piano, but again wouldn't work because you would need to directly link each CPU segment using a brick wire, which again would make the piano 3x bigger at least, and the wire would be a one way signal which wouldn't work if you were using the brick for multiple uses.
This piano is the best thing I've made so far, its a shame that SOMEONE has to say "no named bricks and default events" which for some reason is suppose to mean it needs those or its bad, when in fact it would worsen the build.
