i have my sp 404 hooked up to my Keyboard pa 80, i want to set the Midi on sp 404 to External so when i press the START/STOP button on my keyboard the samples that i made would play at the same time.

i read in the manual to HOLD down the BPM button on sp 404 and then turn on the sampler to chage the midi setting, so i did that but each pad on the sampler is assinged to a key on my keyboard, for example if press A# on my keyboard pad 1 would start playning and so on...

but i want my samples to play when i press the START/STOP button on my keybord, not when play one of the keys on my keyboard.

i also have a YAMAHA SU 700 which has a midi setting that you can set the midi to external and it plays the samples at the same time with my keyboad, but the sp 404 it doesnt...

this is the biggest problem i have with the SP 404
plz somebody help
thanks

if your 404 is successfully slaved to the keyboard, then when you press Play/Stop on the keyboard, you can trigger Patterns on the 404 (ie in Pattern Mode)

the keys of the keyboard can trigger individual pads/samples, but the transport functions (play/stop) can only tell the 404 when to trigger a pattern
it will trigger the last pattern played, at the BPM that your keyboard dictates

for example, if you last played Pattern 8 on the 404, when you press play on the keyboard, it will be Pattern 8 that will begin. if you then select Pattern 6, Pattern 8 will finish and then pattern 6 will begin all at the tempo of the keyboard

does this help?
