Awesome Synthstrom Deluge
A curated list of the Synthstrom Deluge community ecosystem — the open-source community firmware, web tools, editors, shortcut references, and resources for the Deluge synth/sampler/sequencer.
Common questions
All 18 questionsOfficial firmware or community firmware — which should I run?+
The community firmware is where active development happens: it adds features (extra mod destinations, FM, quality-of-life) and fixes ahead of official builds, and is widely considered stable. Official firmware is more conservative. Most engaged users run community firmware; just read the release notes and back up your SD card before flashing.
Grid mode disappeared / a feature is gone after an update — what happened?+
Feature availability and even where things live can shift between firmware versions (official vs community, and across community releases). If a mode "vanished," you likely changed firmware lines or the combo moved — check the release notes for your exact version and the Shortcut Finder. Reflash a known-good version if needed.
How do I record using the internal mic?+
Set the input source to the built-in mic, arm an audio/sample track to record, set monitoring/threshold, and hit record. The usual snag is leaving the input set to line/USB or not arming an audio track — the mic won't capture into a synth track, only an audio/sample track.
Arranger vs Song mode — what's the difference?+
Song mode is the live, loopable clip-launch view; the Arranger lets you lay clips out on a timeline for a fixed arrangement. You build/perform in Song mode and commit a structured arrangement in the Arranger. Many "how do I make a full track" questions are really "switch to the Arranger."
How do I do step / step-input sequencing with an external MIDI controller?+
Map the controller to the Deluge and use note input into the sequencer; for true step entry, use the Deluge's grid for steps and the controller for pitch. Exact step-mode behavior depends on firmware — community firmware has improved external MIDI note/step handling, so check your version.
