Universal Web MIDI editor
C1ZZL3 Envelope Lab
Drag points on either graph to edit stages, or type exact values below. Factory presets turn into a copy the first time you change them. Bounce is the reset preset.
Selected lane: only the active window can be moved.
Point numbers: when stages stack, only the highest number is shown.
Dragging: move a point to change its level and timing together.
Preset status: Local only is stored in this browser; Saved is on the card; Changed has edits not yet saved to the card.
Play / Stop: Play previews the envelope in the browser on a loop. Stop ends the browser preview only.
Pitch Envelopes
Pitch points are capped to the amplitude/PD envelope length. Pitch 1 drives oscillator 1 and Pitch 2 drives oscillator 2 with the full dual-oscillator test firmware.
No CZ pitch source loaded
Pitch 1 / Oscillator 1

Temporary changes: Load RAM, Load Sound Preset, and Send Settings are lost when the card restarts. Save Envelope Only writes the envelope to the selected card slot. Save Sound Preset stores the envelope, slot name, and current settings together when the card supports sound presets; on older firmware it safely falls back to a compatible envelope save. Read Envelopes from Card also restores saved settings when the card supports them. To make the global hardware startup baseline, use the hardware save gesture for your firmware version.
Version compatibility: This lab detects the connected C1ZZL3 firmware and chooses the safest send mode. The editor auto-checks capability before sound-preset saves when needed; Read Settings from Card and Read Envelopes from Card can also refresh the displayed capability. Older firmware receives a collapsed Amp/PD/Pitch payload; newer dual-lane firmware receives the full oscillator lanes and sound-preset data.
