Bassline Editor

v0.22.2
Sound
Lead FM envelope: how the FM amount moves inside every lead note
Tracks
M mutes a track, S solos it. It also applies to the MIDI out, the .mid file and the WAV loop.
Movement
The small knob beside a knob is its attenuator: turn it to let the LFO or the kick move that knob. Right = up, left = down, centre = off. The tiny button under it switches LFO / KICK. These moves are in our own sound and the WAV, not sent to the TD-3.
Pattern helper
Pattern
Bright rows are notes that fit your key and scale. Dark rows will sound off. Number = scale degree (1 = home note). Click a note to set the step, click it again to make it a rest. Accent adds punch, Slide glides into the next step. Space = play / stop.
Pads The pattern as lights, with the playhead running across. Click a pad to switch a step on or off (Accent row: click = accent, Shift-click = slide).
TD-3 bank
Click a slot to load it into the editor. Slots follow the TD-3 layout (group I-IV, 1A-8A and 1B-8B). Each B is a variation of its A. Patterns follow the Key. Nothing is sent to your TD-3.
TD-3 read test (advanced, experimental: reads only, never writes)
MIDI out MIDI in Group Pattern 
Pick the unit's MIDI ports (names with TD-3 are chosen for you), then Read. Compare the result with what the unit's display shows for the same pattern: octave, rests and slides are the open questions.
Export
Device
MIDI out
DAW sync
To sync with a DAW (Cubase etc.) on Windows install a free virtual MIDI cable such as loopMIDI. Make two ports, for example "to DAW" (our notes, set as Bass / Lead / Kick out above) and "from DAW" (the DAW's MIDI clock, set as Clock in here). In the DAW send MIDI clock to "from DAW" and record the "to DAW" port on a MIDI track. Use separate ports for notes and clock. Follow DAW and Send clock cannot be on together.
Each track can go to its own MIDI port and channel (bass 1, lead 2, kick 10 with note 36 by default). Pick the same port for all three to feed one synth or DAW on separate channels. The TD-3 should get the bass only. Mute and solo apply here too. Chrome or Edge.
Drag into your DAW Each lane is its own one-bar MIDI clip with the tempo inside. Drag works in Chrome and Edge; in other browsers click to download.
TD-3-MO: the Cutoff knob also sends cutoff (MIDI CC 74, not yet checked on the hardware). The plain TD-3 has no cutoff control over MIDI.

How to use this

Start in 30 seconds

Press New bass, then Play. Turn Cutoff and Decay while it plays. New kick and New lead add a drum and a melody. Variation gives a related line, Undo brings the last one back.

Playing with the pattern

Click a step to switch it on or off, Shift-click for a slide. Random makes a wilder line; In scale keeps it to the chosen scale. Shift, st and Oct move the whole pattern. Length sets how many steps play.

Saving

Eight pattern slots (A to H) keep your work in this browser. Clearing the browser's data deletes them, so download a backup (.json) now and then.

Taking it to your music

Export a .mid file or a .wav loop, or drag a lane into your DAW (Chrome / Edge). Pick a MIDI port to play your own synth. MIDI needs Chrome or Edge.

TD-3 / TD-3-MO

The bank files and the read test are experimental: not verified on every unit yet. Never send files to a unit that holds patterns you want to keep.

Something wrong?

No sound: press Play first, browsers wait for a click. No MIDI port: use Chrome or Edge and close other apps that use the port. Timing wobbles: keep this tab visible.
