maple classic™ 
i'm so glad deflemask has a hidden undocumented skip_intro feature in the config because i hate that stupid intro and software should not have intros with sound
basically deflemask's ux all comes across as very arrogant to me and i hate that i have no better option for pcengine music creation
i also hate how you can't set it to have a buffer of less than 512 (no unit mentioned) which still has latency in it and if you miss the options menu a bit too much to the right you hit the about button which wiggles a bitcoin donation qr code in your face until you can move your mouse to the tiny button on the middle of the screen to close it
