Welle is a web-based live coding environment that can be used to explore pattern-based electronic music, to quickly try out rhythms and song ideas, to control external MIDI devices and to store, recall and record the musical sessions. Welle is accessible both for sighted musicians as well as for visually impaired or blind musicians

The software centers around an accessible 8-step sample sequencer. It is played by entering commands in the input field in order to simultaneously play available sounds. It allows basic compositional techniques such as simple randomization, snapshots to store the current patterns on-the-fly, as well as to save and recall compositions. Welle enables to record the music directly in the website and makes the recording available for download as webm file. Welle can also be used to control external synthesizers, samplers or DAWs by sending MIDI.

Welle was developed in collaboration with the Institute for the Blind Vienna as part of the research project Tangible Signals by Jens Vetter at the Tangible Music Lab, University of Arts Linz, Austria. The development of Welle was funded with the DOC fellowship by the Austrian Academy of Sciences (ÖAW).
