I´m having a similar problem. Is there any preferences for the export function that I´m overlooking?
I want to sample some of my old non MIDI keyboards for use in a Nord Stage 2 live and in EXS24 for studio use, and also export some of the exsisting EXS 24 sampler instrument to the Nord , but the "Export Sampler Instrument and Sample Files" (in the Edit section of EXS 24) doesn´t seem to help me.
The Nord Sample Editor only reads WAV files up to 44.1kHz, so I need some choices while exporting as well (as most samples seem to be AIFF, and my own is 48kHz). The filenames should include the note (Instrument C#4.WAV) make the process automatic.
I also own Snapper (doesn´t seem to want to read the AIFFs for converting to 44.1kHz) and Samplit 2 (strange flow, makes xxx 1_1_1.wav file names which makes a lot of manual work, and also running into other problems I haven´t solved yet).
I have a iMac 27" (5K, 16GB RAM, 512GB SSD, OSX 10.10.5, Logic Pro X 10.2.0), Universal Apollo 8 Quad (Thunderbolt, latest software), Nord Stage 2 (MIDI via USB, latest software and firmware), and some oldies goldies instruments without MIDI.
