TÓLF purchase and restore
TÓLF is an optional twelve-track sequencer inside RUN4, available as a €4,99 one-time in-app purchase. It requires the base RUN4 app and is not a subscription. The App Store shows your local price before you confirm.
Open Settings > General in RUN4 to buy TÓLF or restore an existing purchase. Restore using the same App Store account that made the purchase. See the TÓLF feature overview for its sound engines, generators, arranging, and Tape integration.
What to include
- RUN4 app version and build number
- iPhone or iPad model and iOS version
- the steps that reproduce the problem
- the AUv3 host or external MIDI/Link setup, if relevant
RUN4 can prepare a local diagnostics export under Settings > General > Diagnostics. Review it before attaching it. Please do not send projects or audio recordings unless they are necessary and you are comfortable sharing them.
Self-help
The app contains a searchable manual under Settings > Help, including recording, Tape, Poly, Disc, Grain, Tone, Color, Air, MIDI, Ableton Link, AUv3, export, and troubleshooting. Unlocking TÓLF adds its complete chapter to the in-app manual.
The same book is on this site: read the RUN4 manual in your browser, search it, or download the illustrated PDF.
