Yes, the port button controls which port to select.
It's a good idea to just go to "edit code" and check the descriptions of the inlets.
There I also explained that the channel that gets delayed/copied, is the channel that is active. The channel that the delay actually goes to is set with the "toChnloffset" selector, which adds or subtracts it's value from the channel that is selected with the edit-bar. So if edit is on for ext-channel 2 up to 4 with the offset set to 6, it will copy/delay the 3 sequences to channel 8 to 10 respectively. Using the from min/max and the to min/max inputs you can select from which part of the sequence you want to copy and to where (and also stretch it if the width is different). It's a good idea to more or less quantize these values to your clock-rate, so you have quick entry to useful start/end positions.
The error comes from that it tries to load a scalebank file. Have you used my scalebank generators? These create a bank of scales on you SDcard, which are then loaded by the polyXL module. Not sure which one it was, but it's a good idea to just load these generator modules once, so the scales are on the SDcard for later use.
Oh, and I just noticed that there are some things missing on the module that's in the library.. guess it's not the latest version..
I shall sync the second version (polymidiXL2), which should have the right setup for those edit/solo/mute/scale bars (each channel is then also scaleable or not) and enable them to be set using midi-controls.
This is the file in which I made/used it, it's still embedded, so maybe you want to interchange it with the polymidiXL2 module which I just uploaded. It also has the scale7generator in the patch to show how to use it (should be able to be swapped with the scale7bank after running the patch once)
