Hey there!

I'm in the process of building a sampler for use with my monome. I've been able to load and trigger samples however, I'm having trouble with the playback of multiple samples at once (for example, presently my patch only does as follows: hold down two buttons with an array, with sample loaded, mapped to each and it will only play either one or the other). I'm using the combination of vline~ and phasor~ and tabread4~.

I'm under the assumption that I either need to "add" the audio ouptut of a read array to a buffer that is continuously playing realtime or find a different algorithm for my patch to be mapping samples to buttons. Currently, I'm using a select~ for the Y-axis [0-7] and a select~ for each row to trigger each individual button on the X-axis (but this feels a little brute-force).

Any suggestions on how best to achieve this?

if you want to trigger multiple samples, you will need multiple vline~/phasor~/tabread~ chains.

Ah. I was hoping it wouldn't come to that. But thank you!!

well, actually,

if all your samples are the same pitch, and are being triggered at the same time,

then you can just use the one phasor~/vline~ chain and then multiple tabread4~'s

Got it. They're not being triggered all at the same time, so I'm using a vline for every sample in a subpatch of the sampler and then the output is all getting thrown~ to the dac~

I still need to work out a bug in my math used for mapping the buttons on my monome (on presses between rows and other distances, a seemingly random number shows up in the Pd console when debugging with print), but after I get that squared away I'll have a very barebones sampler that preloads a samplebank read from a file (thanks to a user from this forum. I'd credit, but I can't find the post I found it from) to show y'all.

You don't have to use a vline/tabread4 for every single sample. You just need to determine the max number of voices that you want to play at any point in time. For example, if you only want to play a max of 4 samples at any point in time, then you only need 4 sample playback subpatches. You can set it up so you load more than 4 samples into your patch, then just use a "set" message to change the buffer you're reading from. I can provide a simple example if you want.

Also, if you're still having trouble with your monome numbers let me know, I can help with that as well.
