Hey Brian / others
I’m struggling with importing midi files to the er-102.
I’m using Logic Pro X on an iMac and have made a composition with 4 midi tracks.
I’ve tried configuration of the .ini file / reducing number of notes / with and without independent midi channel assignments in Logic, but everytime I load the snapshot, only track 1 gets notes, and mostly puts all midi tracks on that same track in a consecutive order.
As I’m working on a mac, i only have the program called “text edit”. I have renamed the file from .rtf to .ini and chenged the file-type, however I’m not sure if thats where the problem is, as i have also tried a number of imports with all four tracks on midi channel 1, 2, 3 and 4, all in same midi file. Maybe i need another program to write .ini files?
I dont know if Logic Pro X is exporting the right midi format, but it seems so - as it’s supposed to export smf type 0, when exporting individual tracks - and smf type 2, when exporting multiple tracks at once.
Here is the composition as a collected midi file, as well as the individual tracks and an .ini file.

I hope you can help! Thanks!
I just noticed that some of the channels actually have two notes on same track at the same time.! Does that have anything to do with it? 
If anyone has recommendations for software i can use on a mac for these tasks, its also very welcome 
thanks!
One thing that I noticed right away, your simple.ini file is still actually an RTF file and not a raw TXT file. If you google “create plain text file on mac”, you can get some instructions on how to create the kind of text files the ER-102 needs. For example:
Also, you should probably avoid filenames with spaces. Instead of “simple 1.mid”, please use “simple-1.mid”.
Hey Brian!
Thanks a lot for your response.! However - I still cant make it work 
So far, best result i managed to get, was only using a short loop of midi notes, exporting four individual SMF0 type midi files / one per track and the right type .ini file. However, pattern 1 is consequently 100 blank patterns on every track, and I cant figure out what the max capacity of notes is (every track on my composition is max 1000 notes - from the manual it’s 10.000 notes per channel max, right?).
What I really want to, is being able to just transfer a simple 4-voice SMF1 to the ER-102 like the “simple mode” from the manual, without .ini files.
Can you tell whats wrong with this midi file? ER-102 says “too big” when im trying to just simply load it into a snapshot.

Where does it say this? The correct maximum is 2000 steps per snapshot.
ahh… okay, so thats the problem? is it per track or in total? I thought it was 10.000 as theres 100 patterns with 100 steps in each, right?
You can have 100 patterns. Yes.
You can put 100 steps in a pattern. Yes.
However, you cannot exceed 2000 steps over all 4 tracks.
Your simple.mid file does have too many steps. Also, the first note of track #1 starts after 192 beats of rest.
I would recommend starting with a much simpler file and work up from there.
Ok, thanks Brian! It makes sense now!
