Begagnad Pittsburgh Modular Percussion Sequencer i mycket bra skick.
Four Channel Programmable Drum Controller
The Pittsburgh Modular Lifeforms Percussion Sequencer is a seriously featured, 4 channel eurorack beat programmer with a classic drum machine style interface. The familiar interface allows for quick mastery of all the features leaving the focus on the music. Seamlessly move around the module tweaking patterns and effects without ever stopping the beat. Easily create new patterns using the live performance or step recording modes, then add one of the powerful pattern effects to each channel to take the sequence to a new level. Designed to integrate into any size eurorack system, simply patch 4 audio signals through the integrated high quality VCAs to create a set of unique percussion voices. Eurorack drum programming has come to life.
Anything is a Drum
Traditionally, patching up a modular drum kit was constrained by the amount of envelope and VCA modules in a system, restricting the number and complexity of percussion voices in most systems. Another option was to use dedicated drum modules that offer a limited sonic palate and few modulation options. The Lifeforms Percussion Sequencer breaks through these barriers by including a percussion tuned analog envelope and VCA on each channel. Patching anything from a basic sine wave to heavily modulated and processed noise sources through the Lifeforms Percussion Sequencer will quickly create a distinctive drum kit that takes full sonic advantage of the unique synthesis options available in any system.

The Mind of a Modern Drum Machine
At the heart of the module is a 4 channel, 32 step beat sequencer designed for live performance. Seamlessly move around the module tweaking patterns and effects without ever stopping the beat. Create and store up to 32 sequences using live performance or step mode recording with pattern lengths varying from 1 to 32 steps. Patterns can be copy and pasted to easily create multiple versions of a beat. The sequencer is driven by an internal tap tempo or external clock source. A dedicated clock in/out jack syncs the sequencer with other modules.
Four Integrated Analog Envelopes and VCAs
Instead of limiting the drums to a few onboard voices or lo-fi samples, the Lifeforms Percussion Sequencer uses an analog envelope and VCA built into each channel to shape any audio source into a percussive instrument. The envelopes are designed with a razor sharp attack and variable decay/release allowing for maximum control over the output of each channel. The envelopes can also be used externally. A short envelope creates a trigger while longer envelopes can be used as a modulation source for oscillators, filters, or anything at all.
6 Adjustable Pattern Effects
The Lifeforms Percussion Sequencer includes 6 unique pattern effects to expand the musical possibilities of traditional grid style beat programming. Effects include everything from swing and beat shifters to glitch and generative algorithms designed to manipulate the sequencer pattern. Each channel can run a unique instance of one pattern effect at a time. A master pattern effect channel is also available that affects all 4 channels of the sequencer. The combination of the channel effect and the master effect allows for up to two effects at a time on each channel. Each effect has one parameter that can be adjusted to dial in the perfect response.
Delays the trigger output of a channel by small divisions of the tempo. Use this effect to create half-step or stutter-step drum triggers. Effect knob controls the amount of channel shift. The range of shift is 1/8th to 7/8ths of a beat.
Probability based glitch effect that creates chaotic gates based on a cascading chance algorithm. The resulting patterns are always in sync with some division of the clock, allowing for stuttering but not disjointed patterns. The probability is set using the effect knob. The range of the glitch effect is minimal to absolute chaos.
Sets the number and timing of triggers created for each active step. The result can be anything from a doubling of the trigger to a rolling effect. The effect knob controls the trigger density.
Create evolving patterns. The morph effect is a probability based algorithm that modifies an existing pattern by adding or removing active steps. The effect knob sets the probability that the pattern will morph.
A classic drum machine effect meant to mimic the feel of a real drummer by shifting the timing of every other step. The effect knob controls the amount of swing.
Temporarily add or drop steps from a pattern. The results are similar to the morph effect but changes to the pattern are not compounded as the pattern plays allowing the resulting pattern to stay anchored to the original sequence. The effect knob sets the probability that a step will be modified.
