Synth One J6 will continue to get better, more updates coming! 0.93.2 07/11/2025 Thanks, everyone!
Just dropped some quick fixes and updates to keep things running smoothly on the latest iOS/iPadOS versions.
Synth One J6 isn’t at version 1.0 yet. We're still cooking! It’s getting better with each update, so stay tuned and keep making noise.
– Analog Matthew 0.93.1 07/07/2025 THANKS EVERYONE, BIG UPDATE!
++ FINE TUNE / DETUNE SLIDERS ++
∙ Each oscillator now has its own Tune & Fine Tune / Detune controls!
∙ Tap the “Tune” button to switch between Semi-Tune and Fine-Tune modes.
∙ Want to reset a tuning slider to zero? Just double-tap it!
∙ Most controls now support double-tap to snap back to the preset’s original value: super handy for experimenting.
++ Detune Details (for Synth Fans!) ++
∙ Detune sliders weren't in the original Juno series, this new feature is inspired by the Jupiter line.
∙ For a classic Juno-style sound: try using just one oscillator, set Unison (SuperSaw) to Detune, or simply adjust the Retro Tuning knob for that vintage vibe.
∙ With Retro Tuning on, each key press slightly varies the tuning: so you might not need the extra detune sliders at all!
++ Better MIDI Preset Change Support ++
∙ We’ve improved compatibility so preset changes via MIDI should now just work: whether you're using a classic DX7 or running Synth One J6 in your iPad as an external instrument in Ableton. ie Change a preset on your synth midi controller, and it should change on Synth One J6
+ Other quick fixes and improvements.
