Doobie v0.17.1
Patch on top of v0.17.0. * Stereo scope inside the tape loop — fed by the existing peak level event (no extra audio plumbing). L deflects up from centre, R down. Bounds now match the tape SVG geometry so the trace sits strictly inside the loop. * Ping-Pong / Freeze / Kill FB chips on one line. * Smaller granular pitch-shifter window for lower perceived latency (~12 ms instead of ~50 ms — fits live use better).
