hi luis -

this should be very easy to do. the midi note triggers an instrument 
instance, and this instance selects the sample, and applies any other 
transformations. something like:

strset 60, "sample1.wav"
strset 61, "sample2.wav"
...

massign 0, "Play"

instr Play
iSample notnum
iTransp = 100 ;cent
aPlay diskin iSample, cent(iTransp)
out aPlay
endin

this is not tested, but you will know what i mean. not sure, though, in 
your example, how you get the sample and the transposition.

hoe this helps, best -

	joachim

Hi Luis,

Thinking while writing, hope it leas somewhere...

So you have a sample according to say midi pitch 55, you want to play it on the pitch 56 and you want to find the fequancy ratio for diskin2 opcode (kpitch parameter) to get the right pitch modification from the sample 55

then I guess

itrans =

I thought about using tables but also about arrays - I'm not yet familiar with arrays.

Hi Luis,

then I guess

-----------

ifile = p4

iclosest_sample = 55

itrans = cpspch(ifile)/cpspch(iclosest_sample)

diskin2 ifile, itrans

the question is, how to find, which is the closest existing sample.

Perhaps easiest would be to define an array as you already suggested youself

giSampleIndex[] init 100 ; or how many notes you will have

giSampleIndex[55] = 55

giSampleIndex[56] = 55

giSampleIndex[57] = 55

;etc

giSampleIndex[58] = 58

giSampleIndex[59] = 58

Probalby it is more convenient to use genarray for defining the values

iarray genarray istart, iens[, inc]

and then

itrans = cpspch(ifile)/cpspch(giSampleIndex[ifile])

OR

you can define a table, for example with GEN07 (straight lines):

f 1 0 128 -7 0 55 0 0 55 3 55 0 58 4 58 ; etc I hope it is correct, did not check

and then

iclosest_sample tab_i ifile, 1

I myself would brefer the array version - somehow closer to my thinking

Best!

There are better ways to fill array:
