Yes, no problems. Once I get back to my computer I will add an attachment.
OK. Here you go. My TouchOSC template for BBCSO is attached as a zip file in case it is of use.
The template has 3 pages (images attached), but most things can be done on the first page. You access the 3 pages using the 3 buttons across the top (BBC keyswitches, BBC Percusion, DCPImages Chromatic). The pictures are probably self-explanatory, but I have added explanations below in case it helps.
Page 1 BBCSO Instrumental Controls
* The left of the page has sliders and an XYPad. The XY Pad sliders are also separated out above in case that becomes more convenient or to help with midilearn.
* The right of the page has three columns labelled Woodwinds, Brass and Strings. These are the BBCSO articulations.
* There is a little redundancy here because the keyswitches for the different groups are the same, but the labels help you to see what articulation you are triggering. Most keyswitches are shared with several instruments. Where they vary you will see the a second name listed For example, Falls and Runs in woodwinds only apply to Piccolos. The keyswitches for the Cimbassos (Cbo) are non-standard, so while they use the same keys, their articulations are listed in orange. Same goes for the Trombones (Tb). Keyswitches marked with a star such as multi-tongue* only apply to certain instruments.
* Towards the centre are keys labelled from C0 to C7 these are midi notes. I find them useful to check that everything is connected and to confirm the octave range of the loaded instrument. CC64 typically triggers the sustain.
Page 2 BBCSO Percussion Controls
* The lower left of the page shows the sliders that are used in BBCSO Percission. Not all sliders apply to all instruments. For example, instruments which play Rolls usually require 'CC17 release' as does Bibisgliando for harp.
* The right contains midi note pads (from notes C2 to B5) to play percussion, but keep in mind that iPad/TouchOSC does not handle velocity well so you will probably prefer to use your keyboard or edit velocities later.
* The buttons outlines in blue are the articulations. Many articulations are shared so the instruments are grouped and labelled in Yellow below. Some only apply to single instruments and are marked (eg Hits Damped# for Tubular Bells; Vibraphone* only has hits; Harp has GlissFX and Bibisgliando*). Note that there is also a button next to Harp to set the direction of the Gliss (UP or DOWN). This is arbitrarily attached to CC3 and you will need to midilearn this in the BBCSO Plugin.
* The buttons outlined in purple are for the untuned percussion.
Page 3 Chromatic keys
* This set is generic and can be used with any plugin.
* Blue keyswitches are for articulations from C-2 to B-1.
* Red keys are chromatic notes from C0 to C8 in case you want to enter musical notes. Elsewhere I have adapted these keys for different scales (including Akebono, Double Harmonic, Major & Minor Pentatonic etc). I have not included these here to avoid confusion, but feel free to make your own modifications.
* Because TouchOSC does not handle velocity well, you would probably prefer to enter notes from a keyboard.
I find this system works really well and is very portable, which is good because in normal times I do a lot of travelling. You can connect your iPad to your computer with Bluetooth, But I recommend USB.
Hope this is useful,
David
