FROM THE LAB: Next Friday, we’re launching a new live streaming series!! Stay tuned!

One of the few modes that we have not yet explored in Ornament & Crime is the Copier Maschine mode, which operates as a 4 channel Analog Shift Register. We’ve examined Piqued, Low Rents, Harrington 1200 and Quadraturia modes already, each fascinating and useful in their own ways. Copier Maschine combines the scale and pitch quantizing functions used in Quantermain mode with the Analog Shift Register, a complex, cascading form of Sample & Hold.

From the Ornament & Crime github manual

In essence, then, ASR mode works as a four-stage sample-and-hold module. Feed a pulse into the left-most digital input (TR1), and some CV signal (LFO, ADSR, etc) into the leftmost CV input (CV1): on receiving a/the clock, the DAC outputs will be updated, ASR-style: the current sample (S(0)) will be present at output A, the previous samples shifted down the remaining outputs (S(-1) > B, S(-2) > C, S(-3) > D).

Each time the unit is triggered, the channel A output samples the CV1 input, passing along the previously held voltage to channel B. Channel B does the same, passing it’s previously held voltage to channel C, which holds the same voltage as channel A did 2 steps prior. Channel C passes along to channel D, as this cascading series of sampled and held voltages continues.

These voltages can be quantized to a pre-existing traditional (or non-traditional) scale, or you can create your own by using the Scale Mask function, allowing certain scale tones to be removed from the scale. These patterns can of masked notes can be rotated by panel controls or via CV input 3, for even more complexity.

What are you using for Analog Shift Registers or Sample & Hold? Let us know in the comments!

Tomorrow, we’ll be announcing a new live streaming video series, scheduled to begin next Friday, August 12th! Stay tuned for more details!!
