Hello again! I don’t want to reopen the discussion about annoying flash. But there is a beautiful flash based instrumen ToneMatrixs from Andre Michelle. I would say a flash-audio guru. You may know him from Hobnox-audiotools. He created a matrix step sequencer and synth similar to the Tenori-On or the Monome.
Check out the single instrument or the whole virtual studio:
Yesterday I stumbled upon a interesting web service called Myna at Aviary.com.
Myna mixing
I think this web application should not be considered as an online sound editor. Better call Myna a online remixing application. You can use tracks from a library, your uploaded or recorded files. There are track seperated effects and a mastering section. I think you should try it.
