Sujet de la discussion Bug de voix ?

Salut,

J'ai trouvé une manipe sur un site qui explique comment éviter au synthé de s'emballer quand on lui envoi en midi deux même notes successivement. Ce qu'il faut savoir c'est que le JX réattribue le même canal pour une même note ce qui forcément coupe court à celle d'avant.

Par contre ce que j'ignore de savoir: Est-ce que la manipe fonctionne uniquement grâce à un kit quelconque ou bien sur le synthé d'origine ? ( sachant que le mien est modifié avec un kit organix ).

Voici donc un extrait du site en question

Voice assignment functions and additional patch RAM
The following six functions switch the Omnimode off and make the JX3P respond to MIDI channel 1. The first three leave the JX3P in normal function. The only difference is that the last six LEDS of the tone selector buttons are used to display the voice assignment. 
The functions 4 to 6 are like the functions 1 to 3 but open a third bank for own patch programs if the bank button C or D is pressed. The programs in bank C and D are not touched. The sequencer is not available in this mode, but the sequence is not lost. Also the first two presets are replaced by measuring sounds (saw only on prg 1 and and noise with high resonance for filter tuning on prg. 2.
Description Use this tone selector button
resetting voice assignment: if the same key is pressed two times the same voice will be used. If a key is released its voice will be used for the next keypress. 1 or 4
circular voice assignment: for each new key presses always the next voice will be used. Also if a key is released the voice will not be used for the next keypress unless all other voices are used. 2 or 5
mixed voice assignment: If NO keys is pressed already the first voice(s) is/are used for the sound. If a keys IS pressed already, the voice assignment is like in the circular assignment 3 or 6
Adding Velocity (needs the EPROM Upgrade)
The Amount of the Envelope gets dependent from the MIDI value for the notes velocity. In this mode neither the sequencer nor the keyboard will work. 7
