SampleStack 1.3.3 opens a format that has been locked away in old ReCycle libraries, adds three more instruments, gains a new export, and fixes a Deluge export that was writing the samples but not the preset.
REX files
Drag a ReCycle loop (.rx2, .rex, or .rcy) into a library and SampleStack decodes it. You get a WAV of the loop with a cue point at every slice, and the loop’s original tempo is reported on import.
That matters because the slices then work with everything already in the app: the slice list, per-slice playback, the transient tools, and export to any instrument that reads cue points. A REX library that has been unusable since your last sampler can be sliced, retimed, and sent to hardware like any other sample.
This is import only. The REX SDK has no write side, so there is no REX export.
Roland TR-1000
The TR-1000 takes samples from a USB flash drive, formatted on the TR-1000 itself, with the files sitting in the drive’s root directory. The import browser only reads the root, so SampleStack flags anything you have left in a subfolder, which is the mistake that is easy to make and hard to spot until you are standing at the machine.
Roland publishes no sample rate or bit depth requirement for the TR-1000, and the manual lists no formats at all. So SampleStack deliberately asks for nothing: WAV, AIFF, MP3, FLAC, and M4A all pass, at any rate and depth. Inventing limits would only flag good samples, the same mistake behind the Digitakt length cap fixed in 1.3.2. Collections track the 500 sample slots per project.
Akai S1000 and Rossum SP-1200
Both of these are preparation collections rather than card layouts, because neither machine reads audio files from a card at all.
Akai S1000. The S1000 has no FAT support: its samples live in Akai’s own filesystem on floppy or SCSI, and a floppy emulator’s card holds disk images with that filesystem inside. SampleStack gets the audio right first: 44.1 kHz or 22.05 kHz at 16-bit, and file names inside the S1000’s actual character set, which is 12 characters, upper case, from A-Z, 0-9, space, #, +, -, and .. That naming rule is where hand-prepared Akai libraries usually fail. Stereo is handled the way the S1000 expects, as -L and -R mono pairs, and unpaired files get counted. The S1000 guide covers building the disk image from there.
Rossum SP-1200. The SD card in the reissue holds the sampler’s own sound and sequence files plus vintage .HFE disk images; Rossum’s quickstart guide never mentions WAV. SampleStack converts to 26.04 kHz mono, the rate of the 1987 original kept by the reissue, keeps names within the Disk module’s 16-character display, and totals your durations against roughly 20 seconds of sampling memory. Preparation stays at 16-bit on purpose: a WAV cannot hold 12-bit audio, and the SP-1200’s own reduction to 12 bits is a large part of why it sounds like it does. The SP-1200 guide covers the three routes onto the machine.
Bitwig Studio and Studio One export
Multisampled instruments now export as .multisample files, the open format Bitwig and PreSonus wrote together. Drop one onto a track in Bitwig Studio or Studio One and the instrument is mapped and ready to play.
It is the most faithful export on the list. Key ranges, velocity layers, root notes, fine tuning, gain, sample start points, and loops all survive, and so do round-robins, which no other export format here can express. A kit with three different snare takes stays a kit with three snare takes instead of collapsing to one. The file is self-contained too: the audio is zipped inside it, stored uncompressed so the player can stream straight out of the file.
The format comparison has a new row for round-robins alongside the new column.
Fixes
Deluge multisample export was missing its preset. SampleStack was exporting the WAV files correctly but writing no XML, so the Deluge had nothing to load. You could play the folder with the browser’s MULTi option, but no instrument was created. Export now writes a complete card layout: the audio under SAMPLES/, plus either a synth preset in SYNTHS/ or a kit in KITS/, your choice from the export menu. Exporting onto an SD card or a Deluge collection writes into the card’s own folders; anywhere else you get a card-shaped folder to copy across. Thanks to the user who tested this on hardware and reported it.
SFZ packs with non-UTF-8 text are no longer skipped. The fallback that reads older Latin-1 encoded SFZ files existed but could never be reached, so packs saved with accented characters in their comments or names were passed over during scanning. They load now.
SampleStack 1.3.3 is available now on the Mac App Store.
