snazim sa trosku upgradnut apc aby sa dalo sucasne pouzit v standardnom mode scrollovania+spustania klipov a zaroven ako step sequencer. Cely koncept mam premysleny a step sekvencer v podstate poskladany v abletone, problem ale nastava s prekladom MIDI.
Ako si to predtavujem:
Stlacim button na APC (prepinac medzi normanlnym modom a mojim sekvencerom), cim poviem medzivrstve medzi nim a Abletonom, ze kazdy button z matice ma napr. posunut o 8 kanalov vyssie (kedze jednotlive stlpce tlacidiel su odosielane v kanaloch 1-8, pripocitanim 8 kanalov dostanem najjednoduchsiu novu sadu tlacidiel). To je vlastne cele a po dalsom stlaceni sa to prepne do povodneho modu.
Moje nefunkcne riesenie:
Mam medzi Ableton a APC strceny Processing a MIDI Yoke. V Proceesingu odchytavam z APC MIDI IN vsetky spravy a automaticky ich preposielam na MIDI Yoke OUT #2 a vsetky spravy z MIDI Yoke IN #1 preposielam na APC MIDI OUT (svetielka). V Abletone mam nastaveny ako control surface APC40, ako jeho vstupny kanal mam MIDI Yoke IN #2 a vystupny MIDI Yoke OUT #1. Toto samotne by malo iba premostit komunikaciu medzi Live a APC (hlavne tie ich sysexove handshaky aby sedeli), no z nejakeho dovodu mi to fungovalo asi 10 min a teraz ani bohovi. Pri starte Abletonu zisti, ze ma pripojene apc a vykresli cerveny ramik okolo 5 riadkov (scrollovaci pohlad) ale nereaguje dalej na nic...
Skusal som aj Bome's MIDI Translator, ale ten moze mat len 1 vstup / 1 vystup, co je dost naprd na obojsmernu komunikaciu. Puredata som nejak presvedcil na multi MIDI i/o ale vobec nic som z neho nedostal, resp. mi to hadzalo nejake divne errory ze nie je dost pamate.
Prosim o radu, akokolvek je mozne realizovat to co chcem, ak ste sa s niecim podobnym stretli... Ako idealny pripad sa mi zda ten Processing, akurat nechapem preco to nechce komunikovat
//EDIT: este som zabudol napisat, ze vlastne do Abletonu normalne prichadzaju noty aj CC cez tento moj "filter". Na druhej strane mi proces Live vzdy po vypnuti zostava visiet na pozadi a zere 50%CPU... Bude v tom nejaka kuleha skryta urcite...
//EDIT2: po zufalom skusani zapinania a vypinania to zrazu zacalo fungovat v smere apc > ableton...bo dalsom nahodnom vypinani zapinani to zacalo fungovat kompletne. Zacinam mat pocit ze chyba je bud v Processingovej kniznici RWMidi alebo virualnych kabloch MIDI Yoke (bezim na Win7). Vie niekto o lepsich ekvivalentoch?
Este zdrojak toho nefunkcneho mala co mam:
