Okay, here is the music so far, after the post below...
(here once lay a long dead link, so you must imagine the joy and wonder of its tones!)
I think that more melody and more contrast is needed. It's interesting that the slower tunes in here, the random-like notes, do present a melody but the faster version sounds more babbling. Timing has to be just right, it seems.
Regularity of the timing is a problem. Not just here, but in electronic music generally. There are things that are best conveyed regularly, but there's a lot of missing expression without it. In many ways the fact that an orchestra is lots of individuals playing at once adds feeling in a way that is very time consuming and difficult for one composer/producer to add in a sequencer.
I programmed my own music software, mainly because I could afford a book on programming but not any expensive music software, but I've been very pleased with the results. I want to add a feature to slide and interpolate parameters automatically, notably tempo. Currently I can modulate a parameter using a waveform or set it to a fixed value, but to slide it automatically to a target tempo should make it easy to add timing expression while remaining in control. If I can do it (it's not easy...) it should work for any parameter too and might lead to lots of new effects. Sliding the wet or decay on a reverb effect would be easy and might sound cool.
For now though I must rest. It appears that I'm dangerously anxious and need to recuperate. I've cancelled all but one of my future dates and feel better already. I aspire to be Raphael in all ways but his demise.
