hello,

i have two problems and i want find answers.

first i have midi/ audio device tascam us 428 and doing with it small project. problem with LED. i try find way to send messages from pure data to us 428. in device manual i read this:

Host to US-428 Messages:
1. UPDATE_AUX_FN_LED: F0 4E<UNIT> 12 0D<AUX#> <STATE> F7
2. UPDATE_FN_LED: F0 4E<UNIT> 12 0E <FN#> <STATE>F7
3. UPDATE_ASN_LED: F0 4E<UNIT> 12 0F<STATE> F7

where

<AUX> is in the range [0...3] corresponding to LED's [AUX1*AUX4]
<FN#> is in the range [0...2] corresponding to LED's [FN1*FN3]
<UNIT> Transmit as 0 for now.
<STATE> is either 0x00 (LED OFF) or 0x7F (LED ON)

well i write UPDATE_AUX_FN_LED message in dec 240 78 0 18 13 0 127 247 and put it in message object. o try connect to [midiout] or [ctlout] but my device LED no reaction. how corect send message out and how monitoring it.

SECOND question. i have diferent numbers from two object. for example from one 13 0 and from other 127. how to do formatting like that 13 0 127. i try [append 0] object but get only floating error.

as two the second question first, you might try [pack f 0 f] and hook up the values to the first and third inlets.

the first question kind of depends on your operating system and your midi software setup. Are you using jackd? if not, that's my suggestion.

thank you for quick replay. i'm using mac os leopard.
