Downloaded the offline app. Looking forward to trying out the features. @martin I see how to grab public library presets and import, but what about my private online presets? Is it only via import project? ---

Having fun with the AI feature of the offline editor. Building a preset just got a lot faster! What’s the best way to report things that the AI agent has found about the firmware that it didn’t like/expect? Not sure if it is the agent making wrong assumptions or its a feature of the firmware that could be improved. @martin you can be the judge of that. In building an extended ARP preset the Claude agent found a couple of bugs in its lua script. > Fixed a real bug uncovered while wiring up the new controls: the firmware clamps a control’s **message** minimum to 0 even when the project correctly declares a negative one, which meant `toMidi()` — previously used indiscriminately for every control, including Swing — silently remapped bipolar fader values onto the wrong, non-negative range (swing at the “0% / centered” position was actually evaluating as +40, and every negative swing value was being read as positive). I split the config reader into `cfgList()` (index→label translation, still needed for Pattern/Octaves/Sync/routing lists) and `cfgValue()` (a straight, unmangled display-value read for every proportional fader: Tempo, Gate, Swing, Chance, and the two new Transpose controls), and re-pointed every call site accordingly — this was a pre-existing defect in Swing, not something introduced by Transpose, but it only became visible once the Transpose tests demanded exact arithmetic. > Found another instance of the same class of bug: the firmware stores a list item’s negative `value` as an **unsigned 16-bit wraparound** (e.g. `-2` becomes `65534`), so `toMidi()` on the new Octave list returns huge positive numbers instead of negative ones. Fixing `cfgList()` to un-wrap that. > > Clean. Transpose Octave is now a 5-item list (-2, -1, 0, +1, +2 Oct) instead of a fader, so it’s picked exactly rather than hunted for on a dial. Converting it surfaced a third instance of the same firmware quirk: a list item’s _negative_ label value comes back from `toMidi()` wrapped as an unsigned 16-bit number (−2 reads as 65534), so I added the standard two’s-complement unwrap to `cfgList()` — this makes negative-valued lists safe in general, not just for this one control. Also, “ParameterMap::forget: cannot remove file” cache messages appear on every preset. Seems harmless but unneccessary? ---

> [@kiwigrass](#): > > @martin you can be the judge of that. In building an extended ARP preset the Claude agent found a couple of bugs in its lua script. All three are wrong assumptions, stemming from one particular misunderstanding. I made changes to the embedded AI reference to prevent it.

@martin What does this mean? > The reply was cut off before it finished - the turn reached its output limit. Nothing was changed. Try again, or ask for a smaller step. Getting it frequently for what seem to me like pretty small tasks. $ spent each time. ---

Is it possible to connect to an OpenAI account? I have access to most LLMs via work but the API key they provide is for OpenAI models. ---

> [@kiwigrass](#): > > The reply was cut off before it finished - the turn reached its output limit. Nothing was changed. Try again, or ask for a smaller step. There is a “safety” limit that stops the work to prevent excessive charges. I was not able to reach that during my work 😉 I will change it so that it warns you but it will not stop it - because it is actually quite a silly idea. Would you be willing to share (PM) URL or project Id and examples of prompts that ran into that issue? ---

Yes. I’ve gone a bit mad with asking the AI agent to do things 🤖 . I think sometimes the timeout happens because for some reason the E1 and the app lose connection. The agent says there is not a prob at their end, and when I exit I see the app reporting that the E1 is not connected. But I have not systematically tested that. I think sometimes it times out just because I have given it too big a task. Breaking into smaller tasks often avoided repeating the timeout. Anyway, a warning would be useful. Maybe also a hard timeout option that the user can set? So far I have used it to build a pretty sophisticated ARP and chord/harmonizer engine with chord shapes/inversions, and SATB choir-type harmonization that I can use with any synth rather than relying on the synths often limited set of built-in ARP and Chord tools. The biggest advantage I see is the fact that it can load the preset and conduct tests directly versus me constantly cutting and pasting. ---

I will post to public library when finished. Still working on a few ideas and making sure there aren’t any UI or musical bugs. It’s only 1 page but close to 1600 lines of code. One nice thing is that the agent can conduct a battery of functional tests (currently 80) on the preset before signing off on a change. But it is not a musician. ---

AI assistant added some labels and AI tells me the controller’s screen font has no glyph for ♮ (U+266E) or ♯ (U+266F) at all, so they render as nothing. Can that be changed @martin? We found a workaround. But the symbols would be useful. ---

Here you go. Still some things to test and add but lets call this a working draft. [Electra One App](https://app.electra.one/preset/4yn8h6FD8mHN55ahrEqp) Let me know if you get it working OK. In terms of what it does there is a fairly detailed description. But the TLDR version is: If you have a poly synth and one finger then you can make chord voicings or 4-part harmonies, and run them through an ARP that has various rhythmic options. Its only 2 pages of controls but close to 2500 lines of lua. Absolutely not possible without 🤖 . Enjoy! ---
