Speaker rename (production device has a full audio circuit, not a buzzer): - MUTE_BUZZER -> MUTE_SPEAKER, self.buz -> self.spk, P_BUZ -> P_SPK - New SPEAKER_AUTO_MUTE flag (default True): mute the speaker when a MIDI host is detected (the old hardcoded behavior; now a setting). Gapless seam between tracks (Continue): - _prepare_next() pre-parses the next playlist item during the LAST bar so the swap is allocation-free. _do_advance() swaps lanes/bpm/bars/ramp/trainer in with lanes[0]['next'] = seam_t (the wall-clock time of the boundary step we just hit), no _reset_clock - the next tick fires step 0 of the new track exactly at the boundary. tick() breaks out at the seam so the old voice's boundary beat is NOT fired (it'd be the new track's step 0 a few ms later). Visuals (build_grid + draws) are deferred one display-refresh cycle behind the audio via _need_redraw, so the audio doesn't wait for them. Continuous ramp: - Replaced the bar-boundary set_bpm step with per-master-step linear interpolation: bpm = _ramp_base + amt * ((m_steps/mlen) % bars) / ramp.every (clamped 30..300). The integer-clamped bpm glides smoothly across the segment. draw_bpm() is now lazy (skips the bitmap alloc if the displayed integer hasn't changed), and the periodic meter tick in run() also redraws BPM so the big number follows the ramp. MIDI Clock Out (master): - New flags: MIDI_CHANNEL (default 10 = GM drum), MIDI_CLOCK_OUT (default OFF), MIDI_CLOCK_OUT_TRANSPORT (default ON). midi_send() now uses the configured channel. In tick(), when running + MIDI_CLOCK_OUT, stream 0xF8 at 24 PPQN with the interval computed live from self.bpm (so it follows the continuous ramp). toggle() sends 0xFA on Start and 0xFC on Stop when transport is enabled. Verified in harness: seam keeps lanes[0]['next'] = seam_t (no _reset_clock); ramp 80 glides via +0.25/step (visible as 80->81 in 4 master steps at rmp80/4/4); Clock Out math sound (60/120/180 BPM -> 41.67/20.83/13.89 ms tick interval).
