The ESX24 was designed to handle AKAI, even had the menu for this in the past and Emagic was assisting with software developers to convert even more libraries before Apple purchased Emagic.
I have allot of experience with all the hardware samplers, mainly AKAI, E-MU and ROLAND., converting those formats was on Emagic's agenda since the late 1990s., the challenge was to get the conversions to emulate the hardware, things like signature effects or components used to deliver the sound the hardware was known for.
So my point is that the samples themselves are nothing compared to the hardware, which I expect to see more of this year after Roland rolled out the JV080 and AKAI beefed up their MPC stuff.
My library is enormous, 5TB, cds-dvds since the 90s in multiple formats while mainly converted to ESX24, but my library is not just samples of known brand names, I helped convert any format to built templates for producers who also traded between each other during artist development, so I have sample libraries which are built around artists, their identity and brand as well via the esx24 because it contained features and SOUNDED clear and loud., hope this explains my concern.
But the logic SAMPLER is not only failing to open instruments I created from AKAI etc conversions, meaning lacking the AKAI growl that the ESX24 used to maintain., the new SAMPLER is failing to open allot of things correctly, maybe they remapped filters ?, for example, the decay and release are off pads with few samples where off, the volume playback way too low, i had to add the gain plug in and a “Plugin Alliance“ maag eq to regain what i had originally tweaked to be as close or identical to the origina.
Anyway just sharing what I found out since discovering this forum.
