Sitar, hearing voices, Miniaudicle
by Kassen 02 Dec '07

Dear ChucKists, Last night I was fooling around with some STK instruments and it looks like Sitar needs some attention. First of all Sitar.pluck() doesn't.... well, pluck. Sitar.moteOn() does pluck and as far as I can see .noteOn could simply be refered to by .pluck(). Second one is slightly more complicated and turns out to be downright dangerous. I accidentally send Sitar some every low notes (in the bottom octave of the MIDI range) and this results in a error that the delay line is too short. Strangely StifKarp doesn't do the same (that one "plucks" as well). This gets dangerous as I believe Sitar will report on this issue for every sample so that's 44 Kilo-errors per second. This was too much for the poor MiniAudicle to deal with and I had to quit it. If it's intended behaviour that Sitar has a minimum frequency (for example because real sitars don't go into the very low range either) it would be bettter to have a sanity check on the frequency before this happens. I could probably fix these myself tomorow and send in the fixed STK Ugens cpp file if that would be helpfull? Next up; VoicForm's documentation doesn't include any mention of the allowed phonemes (sp?) and the only way that I could find them was read the source. Without those this Ugens is almost unusable for non-random usage so that probably needs a fix. I realise, BTW, that figuring out the parameters is time-consuming and probably boring as well but wouldn't it be a lot of fun if ChucK could say it's own name? I tried to persuade it to do that but I think we are short a few sounds.Generally we don't seem to have any plosives or "C"/"k" type clicking sounds so that"s no "chucK', "spork" or "crash" maybe "shred" would be possible. It's kinda trivial but it would be so much fun for demonstrations. I could submit a sugested addition for the docs to the WiKi as well tomorow, the source is quite clear on this once you know your way around. Finally, I did some more testing and I'm now sure that on XP the Mini affects keyboard settings. More speciffically on startup the Mini switches the keyboard layout in the "langiuage bar" to the default one that XP asumes on startup. This can get anoying; my default setting is the Dutch one so I can use my trusty IBM model M but the laptop itself has a US layout so when traveling lightly ( a Model M clocks in at 2.5KG, roughly 5 pounds) I use the US layout. It gets iritating if the Mini keeps switching this back to NL every time it's started (which can get frequent when hunting bugs), especially as I can't see a reason for that. Note that characters like "=" and ">" are in different places on various layouts, as are all the brackets.... It also looks like the Mini doesn't use XP's clip-board so pasting from the Mini to other aplications is impossible, it's also not possible to use "copy", re-start the Mini (or crash it!), then paste. So, that's it, quite a few issues for a 1.5::hour session but that's how it goes :-) Yours, Kas.

Better explain Myself about kb triggering.

Thanks for all the help first of all I played around with the kb.ck in the hid folder and saw that it typed out the letters i pressed so i can use the same setup and say omodify it to trigger for a example when press A triggers a SinOsc to play a freq for say 1 sec ? About the variable question sorry about that I ment a char array like in C++ thanks again . Gabriel aka ALPHACORE --------------------------------- Be a better pen pal.

thank you for the help I think I understand it now I'll read the Kb.ck file and play around with it as far as Charcter variables in think you already answered it thanks Again..

Date: Fri, 30 Nov 2007 19:58:37 +0100 To: "ChucK Users Mailing List" <chuck-users(a)lists.cs.princeton.edu> Hi, Alpha! My question is this Can I say create a Osc with setting that I want which i know how to do But can i say route it to the computer keyboard say trigger it by pressing the letter A Yes, you can. This is quite easy. First thing to do would be to have a look at kb.ck in the /examples/hid/ folder, this will teach you how to use the keyboard as a input device. Run that, press the key you'd like to use and see what id it has. You then include a shred that reads from the keyboard like that file does, write some rules to detect the keys you are interested in and link those to commands like; if(msg.which == my_keynumber) my_envelope.keyOn; Quite easy once you get the hang of it. or can I just setup a char. variable to trigger it? I don't quite understand this question, could you re-phrase it? What do you mean by "char. variable"? Yours, Kas.
