The Stage Shift allows you to pick other stage values within the pattern – even from stages that you’re not playing! It can be nice to add a very controlled variation to your melody while still being able to get back to the original version.⁠

However, if we use a random CV over a single-stage pattern, the stages to be picked will highly depend on the CV nature: in this case, we’re using a random S&H from SAPÈL which has a Gaussian probability distribution (like we’d expect from an analog noise). As a result, some stages are more likely to be played, while others aren’t.⁠

If that’s not what you want, consider adding all the stages to the sequence! You’ll thus shift the Gaussian peak at every stage, and obtain a uniform probability distribution.⁠

This is part of a series based on an idea by Gattobus. You can hear a similar technique being used in his composition ‘Chances’.

INGREDIENTS

• 1 USTA
• 1 SAPÈL
• 1 BRENSO (Optional)
• 2 FALISTRI (Optional)
• CGM (Optional)

DIRECTIONS

1. Set up a sequence on the USTA sequencer. In this example, we are using four voices: Track 1 plays the bass, track 2 plays the lead, and tracks 3 and 4 provide a rhythmic background of a few notes. For the basics of sequence setup, check CV, Gate, Length. In this patch, we used SAPÈL’s clock for all the tracks (see Clock and Ratio)
2. Enter Track 2’s menu and scroll until the Stage Shift voice. Assign it to CV A input.
3. Set all the stages’ length to 0 except for the first one. You can use the ‘Set All’ button to speed up the process.
4. Patch SAPÈL’s S&H output to USTA’s CV A input.
   (Observe how some notes are more likely to happen thanks to the gaussian distribution of SAPÈL’s analog noise).
5. Now bring back the remaining stage.
   (All the notes will have a uniform probability distribution.)
