Indeed - I'd love to find out more about the community and all the different things they are doing with Yoshimi.

Well, I must say I haven't thought of that, but surely it still needs someone to manage the forum, dispose of spammers etc. and that's not going to be me. Indeed, I'm so saturated with this stuff, that from Wednesday through to the following Monday, I will be taking a sabbatical from all things technological, meandering around the New Forest.

Depends how you set it up and what you want it to do really. The world is very much your mollusc.

Well, after my break from all things tech and a mental reset, I've decided that this is yet another thing I simply can't get involved in. I've put a post on the Yoshimi email list, asking if people are interested, and for someone to to take it on. If someone does, then I'll probably contribute from time to time but that's all.

Currently, this is what I'm already involved in:
Yoshimi development (the biggie)
Yoshimi Advanced User Manual
Yoshimi Website
Yoshimi Users list
Yoshimi Pi development
New Yoshimi Pi website
Preparation for November Linux Audio Conference (assuming it takes place).

And what do you do in your spare time?
;)

I would suggest that with the blog the first thing is to keep it simple, the second is to encourage your contributors to pace themselves.

Unfortunately a bug has been discovered concerning detune. This gives the wrong detune degrees for both fine and coarse detuning. However it only affects AddSynth Global. The individual voices, modulators, SubSynth and PadSynth are fine.

This has been present for over a year, so affects all Yoshimi Pi units out there. It is corrected in the current 'master' for those wanting to fetch it.

For those diving into the instrument editors...

I had someone rather puzzled by the fact that he didn't seem to get much response from the frequency envelope controls. The reason was that he had a very short amplitude envelope.

An excerpt from the notes!

"
The first thing to keep in mind is that amplitude envelopes (particularly release time) set the point at which a note ceases. Frequency/filter envelopes can be shorter, so their effect stops part way, but if they are longer, the last part will be ineffective.

Across all three engines, and kits (if kit mode is active) it is whichever is the longest that sets the overall time of the note, and you may well hear other sections stop if the times are sufficiently different.

Also, within AddSynth itself, it is which ever voice has the longest envelope that sets the overall voice time, and if you set voices with very different characteristics you can hear the shorter ones finish before the overall sound stops. Bear in mind, that each voice can also have a start delay set, so you can get a late sound pickup that is then the last bit you hear, even if it's quite short. However, if the start time of one voice is after all the others have finished it will never sound.

This sort of idea works best with 'Forced Release' disabled.

An unexpected twist to this, is that taking the combined voice envelope time against the main (global) AddSynth envelope, although attack and decay times follow the above pattern, it is which ever (the voice group or the global value) has the shortest release that sets the AddSynth time as a whole. This can really catch you out!

With regard to the modulator amplitude envelopes. They don't change the overall time, but if they are shorter than their voice length (or any voice that the modulator is slaved to) the modulation may end a bit strangely. If they are longer, then part of their action will be missed. Also, when using the Morph type, you must have an envelope set, as this is what controls the way the sound morphs between the voice oscillator and the modulator one.

Finally, there is what I believe to be a bug that goes back to Zyn 2.2.1 - original Zyn :)

If an AddSynth voice is enabled, it's amplitude envelope time is active, even if the envelope is apparently deactivated and not editable. Oh, and by default all the voice times are quite long, so again you could be puzzled as to why a sound is longer than you expected. Because this has always been there I don't propose to change it. To do so would quite likely alter many existing instrument patches, but do keep it in mind.

Thanks Will - there's a huge amount to take in with Yoshimi Pi, so your gentle remainders and clarifications are most welcome!
