Does anyone know the limit numbers for adding Sampler, Synthesis & Drum patches?
I remember hearing something about 25 sampler patches (my op-1 stops at 25), but I can’t remember the other limits.
This is a 2011 post from the old ohpeewon forum (btw, the server is still active, just not published through a DNS):
From TE support:The OP-1 can store the following:
Max Synth Sampler patches = 42
Max Synth Synthesis patches = 100
Max Drum Patches = 42
I guess you need to subtract the factory presets from the figures above…

Ok great, thanks punji!
what’s the ip of the old server?
Edit your “hosts” file (located at C:\Windows\System32\drivers\etc\hosts on Windows or /private/etc/hosts on Mac) and add the following line at the end:
69.163.224.179 ohpeewon.com
Now try to open the old site in your browser as before, like “http://ohpeewon.com”.
This didn’t work for me on a mac Punji…I wasn’t allowed to modify, I tried saving a copy elsewhere and dropping it in but it didn’t work. I want to believe!

I used to know how to do this but have long since forgotten, but this person seems to know:

OS X makes you jump through a few hoops.
Bad news: the old site is not working anymore (you get an advert page instead). 
Is there any way to remove some of the factory presets from the op-1 to make more room?
Sadly no.
People (including myself) had been asking for the option to delete factory presets, but that choice has not been given to us…
You can always nose through the old ohpeewon pages this way…

That’s gonna be really great to look through. I didn’t have a OP-1 back then. Thanks for bringing that up.
Are user synth samples 6 seconds regardless of trim points? Doesn’t seem to be a truncate function and Seems like I can extend ‘end’ point way beyond the end of what I actually recorded on samples which under 6 seconds, which is like 80% of my samples. If so that seems like a pretty weird waste of memory.

Just like the tape and album, and seemingly everything else on the OP-1, I think the samples already have pre-allocated storage spots, which sounds like a very stable and processor-efficient way of organising memory to me.
I’m no expert at these matters, but pre-allocating memory used to be very common in the old days when computers weren’t as snappy as they are today. It means only the pre-allocated memory spot has to be written or read from and the pointer telling the system where to find something is fixed, whereas with a fluid memory organisation, you’d also need to write and read the pointers telling you which memory location to access.
