# pcppcp/op1r > A patcher that modifies the original Teenage Engineering OP-1 firmware R246, adding custom synth engines, FX, sequencer and sample editing tools via a browser-based tool and Python scripts. - Magnitude: 1.3 out of 10 — Steady - Stars: 91 total · +1 star measured 2026-10-15, 00:21–02:37 UTC, ≈ 6 by evening - Star trust: star growth looks organic - Category: Hardware, IoT & robotics · Language: Python · License: GPL-3.0 · Created: 2026-10-09 · Last push: 2026-10-14 - GitHub: https://github.com/pcppcp/op1r · Page: https://gitnova.dev/en/r/pcppcp/op1r ## Useful for - Patch the R246 firmware with new synth engines like supersaw and granular. - Add the euclid sequencer and quad LFO to extend OP-1's sequencing capabilities. - Edit samples and drum kits directly on the device with the built-in sample editor. ## Why it’s here - Star-counter measurements on 2026-10-15 (UTC), 00:21–02:37: 90 → 91 stars (+1). This is the change over that interval. - Estimated end-of-day forecast: about +6 stars, using observed gains and the previous day. - The repository is 6 days old and already has 91 stars. With less than two weeks of history, there's no usual pace to compare the spike against yet. - Top new repositories this week: #187. - Recent forks include notable developers: @ajturner (489 followers). ## Star trust Star growth looks organic. Star-trust labels are heuristics based on the repository’s behavior, not a check of every stargazer. ## Numbers - Forks: 6 - Issues and pull requests: 5 - Watchers: 4 - Average over the last week: 14 per day - Usual pace: too little history (under two weeks) - Stars in the last hour (measured): 1 ## Stars per day, last 7 days (oldest → newest, today is partial) 2026-10-09 … 2026-10-15: 5, 31, 16, 22, 12, 5, 1 ## Spotted in now - Top new repositories this week: #187 ## Similar by description 1. **hugelton/Felucca** — 1.9 · Steady · Hardware, IoT & robotics · C · +1 star measured 2026-10-15, 00:26–02:34 UTC, ≈ 18 by evening Custom firmware for the M-VAVE FM-1 synthesizer: nine engines, four tracks, a 64-step sequencer, effects and a web editor.

It is not a quality score. Days are UTC. “So far today” is a fact; “expected by the end of the day” is a forecast. Summaries and use cases are written by an LLM (DeepSeek V4.1 Flash) from the README and may be inaccurate: verify specific claims (benchmarks, speed, hardware) in the repository itself.
