Handcrafted software instruments from my personal collection

Sforzando the software SFZ sample player

With more controls available than the average clarinet included in orchestral packages, I'm excited to share this new SFZ instrument with my fellow MIDI musicians.



Starting with the Bb Clarinet samples posed by the Philharmonia Orchestra of London, I developed this versatile and highly expressive virtual instrument which weighs in at a whopping 54 MB.


Programmed as a monophonic solo instrument, here are the features that make this a sophisticated woodwind to add to your MIDI arsenal:

  • 508 samples

  • Full authentic clarinet range from D3 (MIDI note #50) to C7 (MIDI note #96)

  • Each note individually sampled with no sample stretching on the primary Legato and Staccato layers

  • 4 velocity layers for Legato, 5 for Staccato

  • Expressive volume control via CC11

  • EQ nasal emphasis via CC23

  • Vibrato available

Full details on each instrument/sound


FB-01 EBass


5 octaves, from C2 (36) to C7 (96), sampled from the legendary Korg workstation module, the X5DR that I bought in the early '90's. This breathy, sample modeling choir is a perfect example of what Korg's acclaimed Ai2 sound engine is capable of.

This is a decidedly “synthy” but musically interesting and useful patch from Yamaha's famous rack-mount digital unit that made professional sampling available to the mass market for the first time in the late '80's. As with the X5DR choir, I've laid out my samples to cover all the keys of a standard 5 octave keyboard.


This is a custom patch I programmed on my CZ-1000 for use in the soundtrack for my musical, “Dorian Gray.” Like the CZ Whistle, this covers 3 octaves – C3 (48) to C6 (84). It's a mysterious, twangy sound with strong 5th overtones which are tuned to the keyboard's pitch centers.


TX16 Scat Voices

TX16 Acoustic Guitar

This is the acoustic guitar patch from the TX16 sampler which drove musicians crazy back in the day. Its unique characteristics still make it very useful, as can be heard in the MP3 demo. The samples are laid out from C2 (36) to C6 (84), giving you a huge range to work with.

This is a really fun collection of scat voices from the TX16 collection, featuring 59 samples that are laid out from D2 (38) to C7 (96).

TX16 Moog Bass

This is another set of TX16 samples that musicians drooled over back in the late '80's – Authentic samples of the legendary Moog Bass. Programmed as a monophonic bass with vibrato available, this covers 3 octaves, from C3 (48) to C6 (84). A timeless sound that will never die!


FB-01 Space

CZ Zap

A highly atmospheric patch from Yamaha's FB-01 module which I've programmed across the width of a standard 5 octave keyboard. It's a crystalline, glass-like “Star Trek” sound. Take a listen to the demo and you'll hear what I mean.

A great patch I programmed on the Casio CZ-1000 following instructions in a CZ patch cook book, it's a unique two part sound which also covers a full 5 octaves. When holding a key down, the result is a thin buzzing sound that really cuts through, and when a key is released, there's a very cool, fast whoosh/thud sound that quickly cuts off. The MP3 demonstrates better than words.


I bought a set of the popular colorful plastic tubes which are now ubiquitous in school music programs nation wide. I set about whacking them, enjoying the satisfying hollow Bonk! sound – so set up a sampling session and came up with this octave of happy sounds which I've set up from middle C (60) to C5 (72). Since the tone varies depending on how hard the tubes are hit, I used two velocity layers. The results? Take a listen – My bet is you'll find a home for this set of samples in your tuned percussion library.
