hello everyone! i’ve built an 8-track groovebox that works entirely in the browser and is free to use: https://tahti.studio/ lurking on this forum a lot, i thought someone here might appreciate it 
some key features:
- sample-based sound generation with support for single-cycle waveforms
- almost all parameters can be modulated on a per-step basis
- each track has a multimode filter, distortion, frequency shifter, sample-rate reducer, and amp envelope
- three freely assignable modulation sources per track (essentially flexible LFOs that can be used in one-shot mode)
- steps have micro-timing, retriggering, probability, and trigger conditions
- tracks can have individual lengths and sequencer speeds (the latter can even be step-modulated, because why not)
- four send effect: chorus, phaser, reverb, delay
- a master compressor and soft clipper
- macro controls for working with all kinds of inputs (check out the shortcuts)
- pattern sharing via secret links (e.g. tahti)
- rendering patterns to .wav
it’s got a default library with some samples and demo patterns made by friends and myself to get you started, but you can also use your own samples. unless you decide to share patterns, everything happens in your browser and nothing is uploaded to a server. unfortunately, it doesn’t currently work on touch devices, only on desktop. i don’t have any kind of documentation yet but i think if you’ve ever used an Elektron box you’ll probably get a hang of things fairly quickly 
play with it and let me know what you think!
