FM Synthesizer coumarin is a fully functional analogue synthesizer in VRChat.
RobertWK’s Review: Like Fractone, this world is a xylophone+synthesizer combination. The instant sound feedback you get from the changes you can make to the output are more obvious and less reliant on the understanding of how different waveforms affect that output. The knobs are well labeled and provide a range of values when changed. One nice feature about this synthesizer is that the instrument definition is listed as a text string on the back so that you can copy and paste it back if you ever need to recall it. The only downside is that this synthesizer does not come with a tracker, so any recording of audio that you do will have to be captured by a stream. (Rating: 7.5)
Katchy’s Review: I think this world along with Fractone probably have the easiest keyboards to actually play in VR since the keys are so spaced out and you use a tool to play it instead of with your fingers. It sounds great and it’s easy to manipulate the sound. Can’t really complain here! (Rating: 7.5)
