Navigating away from the playback interface as the main tab in Safari causes a significant drop in the clock and the randomizer also stops. Everything functions normally when the app is the active tab and reverts back to functioning normally if you move away and click back. Only happens in Safari and functions perfectly in Chrome.

Safari version 14.0.3 (16610.4.3.1.7)

I'd love to be able to start/stop playback using a button or the space bar, currently having to reload the page or close out a tab when I want to stop.

I've come up with a way to use your app to drive external synths and drum machines using WebMIDI (currently supported by Chrome).

There's a squashed commit here that has a rough draft: https://github.com/nagytech/acid-banger/commit/bf0cc4764623ec82bb618f7c13c0655516fc0f6e

I'm wondering if you would be interested in this as a feature. And, if you might have some insight on how you would offer the user the option to select a MIDI output (if found and supported).

I'll continue to clean up my implementation, hopefully it will be less of a hack soon.

Summary

• Notes for saw osc are sent to MIDI channel 8
• Notes for square osc are sent to MIDI channel 9
• Drum tracks are sent to channels 1,2,3 and 4 using note 35

TODO

• Velocity is set to a static value, will need to map this to the appropriate MIDI values
• Filter values, accents and glides are not implemented yet (will need to look up the right CC values for this)
• Different synths will have different retrig rules, so ties (glide) notes might be tricky to implement - I can do what works for me, but no guarantee it works for others.

Hardware

WebMIDI Out -> Digitakt MIDI via USB -> Tracks 1-4 -> Drum Samples
                                        Tracks 10-11 -> MIDI Out -> MIDI to CV -> Synth A/B

Demo

I'd love to sync my Pocket Operators with the Acid Banger. They use some sort of click track on the left channel, same as the Korg Volca line I believe. Would it be possible to add an option to output this? Bonus points for using the audio recording APIs to take sync input.

CC licenses are great for most mediums. Software is a different story.

We recommend against using Creative Commons licenses for software. Instead, we strongly encourage you to use one of the very good software licenses which are already available.

Depending on how careful you'd like to be (and protective of the open source nature of this tool), something like Apache 2.0 (requires only attribution; can be used in closed source) or GPL 3 (requires attribution; cannot be used in closed source) would be better for the code in the repo. Typically FOSS projects apply some sort of FOSS license to their code and a CC license to the documentation and assets.

Really enjoy the project! Thanks so much for sharing

I suspect my assumption that mousedown, mouseup and mousemove events translate 1-1 to touch screen devices to make draggable controls is false.

The butterchurn library can be used to add support for Milkdrop visualizations by connecting up to AudioNodes.

I wish there was a master volume control so I could balance the music with other things im doing on the computer
