IYTTIW sample set

IYTTIW stands for "If You Think This Is Weird". A very unique set based on original trumpet samples. Its diminutive size packs a big sound. Perfect on its own or for doubling other sounds. I played and recorded some trumpet and made samples from the performance. I then resynthesized the samples to alter their timbral and spectral quality. In some, you can still hear the trumpet and there are others where their origin is well hidden.

It was originally a commercial set that is now free. It contains 41 regular multi-sampled programs without velocity. All are short sounds, no pads here. It's very well-suited for staccato playing and sequencing.

It has 551 samples for a small size of 15.7 MB and is offered in the following formats: wav, sfz, soundfont, Native Instruments Kontakt 3.5 or better (full version, not the free Player).

All formats are in this single DOWNLOAD

Kontakt 3.5 version additionally has 21 multis and 50 instruments made with the Tone and Time machines that greatly expand its sound palette. These stretched instruments usually have longer durations than the basic samples, 14 of them with sustain.

Here's an audio example using a few samples with pitch randomization: IYTTIW in QuadZamp
