Question: Re : Midi clock. Thank you, Justin. Any plan to have "proper" (standard) Midi Clock support (Reaper beig able to receive Midi clock from a hardware sequencer/synth) ?

No, REAPER needs predictability. Comment...

Question: Re : Midi clock. Thank you so much, i wasn't aware about that. However, i have several drop outs, and it seems to have some lag at while starting playback, and that Reaper doesn't display the right tempo (it keeps displaying the default 120bpm while the midi clock was set at 108bpm), so if i record my performance as audio, will it be tagged as 120bpm, or 108

It won't read tempo from the clock, just uses it to synchronize, you need to manually match the tempos. Comment...

No, it can slave to midi clock but can't adapt to the rate changes, as it requires tempo to be predictable. Comment...

Question: There have been several examples in the past where novel developments in technology have inadvertently contributed to paradigm shifts within the arts. i.e the relationship between 808 et al with electronic music, or the electric guitar.

Probably not AVS exactly, but something like the visualization in WHUMP (which is user editable in javascript), maybe spending more time on some of the effects, and maybe making it more modular? Comment...

Wake up in the morning, make coffee, eat some yogurt, work (programming, reading forums, handling a tiny percentage of customer service things), eat something for lunch, maybe go to the studio and work/record, maybe stay home and work, maybe go wander around the city with Al, then maybe a run in the late afternoon, dinner, some TV programs (Better Call Saul, if I'm lucky!), bed. With more working throughout there too (hard to avoid). Comment...

Question: Hi! I'm attempting to code an audio mixer - (full question below)

Hi! I'm attempting to code an audio mixer - I'm using C++ and SDL2, filling a
 buffer with a callback function. I can't seem to find an explaination of how to
adjust gain over time - with * 1.0f being no change, * 0.5f being about -6dB, etc..
Doing it in one sample introduces a click, as I'd expect.. doing a linear interpolation
over a number of samples also [truncated]
