Hi all,
I've been working on a simple browser-based music workstation called HM Tracker, and wanted to share it with the KVR community.

You can test it out here: https://manager.kiekko.pro/tracker/ (https://manager.kiekko.pro/tracker/)

The core idea: all sound is generated in real-time from oscillators using the Web Audio API (no samples, no plugins, just open the link and hit play).

Current features:

• 8 channels: harmony, arp, kick, hihat, snare, bass, lead, FX
• Pattern-based step sequencer (tracker-style interface)
• ~60 built-in instrument presets across all channels (everything from 808 kicks to supersaw pads to acid bass)
• Global effects chain: tempo-synced delay, convolution reverb, master compressor, sidechain pumping
• Chord/key system with harmony modes
• Save/load your own tracks as JSON

The export feature is why this was actually made in the first place (used it to create simple looping game music ) - you can export your track as a standalone JavaScript audio engine (start/stop/isPlaying) or render to WAV. The JS export is fully self-contained with zero dependencies, which makes it handy for web projects, or anywhere you need procedural music without shipping sample files. Obviously this is not a proper DAW, but something simple to play with.

Would love to hear what you think. Especially from fellow tracker users. Any feedback on workflow, sound quality, or missing features is very welcome!

Now I think I dare to say HM Tracker is nearing DAW (or should I say WAW aka Web Audio Workstation) territory.

Instrument channels are now dynamic, possibility to add up to 16 channels. Bar count is not fixed to 8 anymore, now up to 128 bars is supported.

Each individual channel now has mixer, exposing basic EQ, delay/reverb sends to master bus, Haas and Microshift wideners, and synth features like wavetable, unison, filters, vibrato and distortion.

Master bus mixer has M/S processing (side highpass) and MS/MONO/SIDE monitor. Delay settings (time, feedback, tone, drive and mix) to unify adjustments for those instruments which has sends set. Currently there is just one "master bus", but that's at least a start.

Another big upgrade was made to grid editor. There is now drag&drop support to move multiple notes (or single note with Shift-click). Per-step edit has settings for master bus sends.

Pad instrument channel was added, UI received lots of polish and basic "section arrangement labels" were also added.
