Common Music (CM) is another interesting composition system (http://commonmusic.sourceforge.net), and a recent revision of the old CM version 2 (https://github.com/ormf/cm), which was still implemented in Common Lisp (in contrast to later versions defined in Scheme) can be loaded into and used alongside Opusmodus 1.2 without problems. This was possible primarily due to a largely revised load mechanism of the old CM sources.
With the new Opusmodus 1.3 this is not possible any more. It seems the problem is caused by the fact that :CLM (and a number of variants) are still added to *features*, but there is no CLM package anymore. I cannot see the Opusmodus sources, but I assume that all CLM definitions have been added directly to the Opusmodus package. Anyway, due to the present feature CM assumes that CLM is there, but then cannot find its package.
Anyway, I found a way around (by changing the relevant feature expressions from #-clm into #-(and clm (not opusmodus)) and will try to have that included in the relevant CM sources at https://github.com/ormf/cm
I have converted many of my scores made in Notion to music xml in order to display them in the Assistant..which is very nice indeed.
I'm wondering if I can convert those xml scores to an Opusmodus score direct or do I have to re-import them as midi? I see I can go the other way..xml to Notion, but cannot find how to go this way or if it's possible.
I found a great app to upload and share your music here is the address you can test it it is much better and classy than Soundcloud
