They're both extremely modern Sample- & Pattern- Libraries for the NI Maschine platform (and you can, of course, use the sample content with any other sampler), made using a truly slutty assortment of gear, both in terms of sound sources as well as in terms of outboard, and with the SSFX-typical obsessive attention to detail. Recorded, edited and processed in 192kHz using ULN-8 and UA 2192, then down-sampled using 64-bit SRC & dithering to 96kHz for Transistor Rhythm and 44.1kHz for Transistor Punch. Did I say obsessive? Make that lunatic: I booked a mastering studio and set optimum SRC and dither parameters for each and every sample individually.
Here are a couple of images of the gear used, for more detail have a look at the manual (this is worth reading even if you HATE reading manuals :afro: ).
SSFX Transistor Rhythm Features 800 Drum- and FX-Samples, organized into 50 Kits (aka Maschine Groups), each of which contains 4 for a total of 200 Rhythms that cover loads of modern genres. These aren't sterile, Hi-Fi or wimpy "sample CD" type drums or Bontempi Arranger rhythms, no re-packaged same-old stuff, it's all fresh and juicy. They pack illegal amounts of punch and groove. Every single drum and FX has been hand-crafted and went through an apartment's worth of gear. It's obvious that I'm slightly biased 
...but let me just say that I set out to make the coolest drums and patterns on the planet. Check out the audio demos and the 3 free kits taken from Transistor Rhythm to see wether I achieved that or not :rockon: .Transistor Rhythm is available now as a download for just €59 including VAT if appliccable. Plus, there's a 20% discount for users of Transistor Punch.
While making Transistor Rhythm, I spoke to Native Instruments and we decided to take a part of the Transistor Rhythm material, add lots more and make a sister product since they were planning to do Maschine content anyway and we had delivered parts of the factory library already. What we came up with is
NI Transistor Punch which comes with 30 Kits and 120 Patterns targeted specifically at modern european electronic styles, about 50 of which have been programmed by my long-time friend and studio neighbor Martin Buttrich, known for his hot club releases on Desolat and other labels, as well as for his production work with artists like Loco Dice and Timo Maas. Also included are 120 one-shots straight from my Kyma and Modular synth, as well as 20 multi-sampled synths organized into 50 Maschine Sounds. Add 5 demo projects (which contain loads more patterns, lines etc) and 20 sequenced multi-effects and you get Transistor Punch. Available now from NI for €49 incl. VAT if appliccable.Both packs are designed for Maschine v1.6 (not included...now who would have guessed that?), but the sample material will work with any sampler out there.
Enjoy!
