It should be noted that x|k who is the maker of the midines is working on midines 2.0, which will have substantially improved features. It will possibly involve a built in tracker software, for instance, and there is talk of an FPGA to emulate the mappers that make NES music so great. See, the RICOH 2a03 only has 5 channels.. 2 pulse, 1 tri, 1 w/n, and 1 dpcm sample channel. But loads of games had memmory mappers allowing for larger storage, but that also integrated extra oscillators. The japanese famicom had a channel that took the combined output of audio channels on the cart, and fed them through the audio out along with the 5 2a03 channels. Not sure if the american nes can use the extra mappers for audio.. Anyhow.. the midines 2.0 is supposed to respond to many needs people who use it have brought to x|k's attention. Like, having to program volume envelopes and pulse width changes into your sequencer, rather than having instruments that contain that information stored in the cart by some means (like patches). One solution, for current midines users, is to use a tracker like renoise with midi out. Famitracker i believe has midiout too. Then you can do whatever the hell you can possibly think of with the real midines. Famitracker actually has pretty good instrument settings screens. Again, i'm not 100% sure if it has midi out. Though, famitracker shoudl deffinately work on creating integration with midines. That seems onyl logical.
