The Beat Goes Virtual


Apple Ultrabeat

It’s a given that the transition from dedicated hardware samplers and synthesizers to virtual software-driven instruments brings more of your music production right to your desktop. Samplers were among the first instruments to make the move to computer-based workstations. For years, musicians have been using drum and percussion samples to create rhythms and effects; the evolution of the virtual drum machine was only a matter of time.

Virtual drum machines or rhythm composers (call them what you may) have expanded with functions that go considerably beyond traditional drum machines or samplers. For example, velocity switching among samples (the harder the “hit,” the more the sound character changes) typically once involved two or three different sounds. Today, there might be a dozen or more samples in the mix — with distinct samples for right and left hands! With drum/percussion collections often including thousands of samples, some applications now include database tools to help keep track of all these sounds.

Another interesting development is incorporating “groove agents” that enable you to go beyond traditional beat patterns and loops to encompass entire rhythm sections that form a song’s foundation. If you’re looking for an instrument, distinguishing between a virtual drum machine and a groove box/remix application can be tricky. For the buyer’s guide assembled below, we’ve defined virtual drum machines as products that can import samples and velocity-switch among them, assuming that the instrument in question wasn’t originally intended as strictly a synthesis-based system. Yet, while lacking these particular characteristics, Spectrasonics‘ ( Stylus RMX is certainly noteworthy and deserves a close look.

We searched for applications that are likely to appeal to audio pros, omitting consumer-grade products. However, Cakewalk‘s ( Kinetic, geared for the remix artist, and Acoustica‘s ( Beatcraft may, nonetheless, be just what you’re looking for. There are some amazing and cool products out there, so let’s get going.

Integrated into Apple‘s ( Logic 7, the Ultrabeat drum synthesizer has full provisions for creating percussion loops or manipulating the samples of instrument sounds. Particularly effective for working in techno, house, hip hop or derivative musical genres, Ultrabeat provides two synchable LFOs, two EQs and four envelopes per voice. The instrument employs subtractive and FM synthesis, noise, modeling and sampling. Its 32-step sequencer with accent is reminiscent of popular early ’80s drum machines. UltraBeat offers 24 drum voices and one voice that can be played chromatically. Among its various effects, filters and EQs is a multimode filter that offers four different 12- or 24dB cut-off modes for tweaking the lower frequencies of instrument sounds.

With the exception of Tsunami, the Hork, Meteor, Psion and Puma drum/percussion modules for Arturia‘s ( Storm PC/Windows music software follow the same basic operation and programming system. The difference lies in the choice of instruments with each module. Hork, for example, employs samples of acoustic drum set instruments, while Psion has samples from electronic kits. Puma is a collection of Latin percussion instruments, and Meteor offers samples from an unidentified drum machine. Instrument pitch and decay can be defined, and each instrument can be controlled by MIDI, shortcuts on the numeric keypad or via the instrument’s Mute and Solo functions. Unlike the other modules, the Tsunami module is a 100-percent synthesized drum machine with eight oscillators — all fitted with various controllers such as amplitude, frequency envelopes and bandpass filters for each sound.
