Valence: focus an extra colour layer around the source

Start with the character of a specific source

A vocal, bass guitar, electric piano or drum room can benefit from valve colour for different reasons. Valence provides several ways to shape that response, so begin with one musical aim: a firmer midrange, a softer edge, or an extra textured layer around the original part. Keep the phrase long enough to include changes in level and register.

Establish a sensible input and choose a topology before making several compensating tone moves. T, P1 and P2 are different valve-path structures; Triode and Pentode are further behaviour choices. Compare them on the same notes so the architecture is an audible decision.

Focus does not isolate the entire valve path

Focus offers Full, Low, Band and High for an additional coloured residual return. Parallel controls that return's contribution. The main valve path still has its own role, and the global Mix is a separate balance between the overall treatment and the direct signal.

Bias and Sag change the nonlinear behaviour. They are worth hearing on both attacks and sustained notes: a setting that adds an appealing edge to a short accent may change a long held note differently. Keep Output or the host's comparison level under control as these interactions develop.

Workflow one: give an electric piano a stronger centre

Use a chord progression with quiet voicings and harder accents, preferably in the arrangement where it needs to sit.

1. Begin with the additional Parallel contribution restrained. Choose a topology and valve mode that support the basic tone.
2. Raise the drive-related level gradually and adjust Bias or Sag one at a time while hearing the attack and sustain.
3. Select Band or another suitable Focus and bring Parallel in for a particular extra colour.
4. Use global Mix to decide how the complete treatment joins the direct performance, then compare at similar loudness.

If the result makes every chord equally dense, reduce the contribution that is filling the gaps. The focused return can be useful without being obvious: its job may be to make the keyboard's centre easier to follow while the direct sound keeps the touch and lower foundation.

Workflow two: a bass with an added upper texture

A bass part can retain a clear foundation while carrying a more audible coloured contribution above it.

1. Set the main valve sound conservatively on the lowest and highest notes of the line.
2. Choose a Focus for the added return and bring Parallel up from a low position. Listen for note definition rather than a louder solo sound.
3. Compare the stereo mode with the actual source. Linked, Dual Mono, Coupled and M/S are different operating choices.
4. Rebalance the global Mix and check the bass with the kick and vocal.

Do not assume that High Focus means the main bass path receives no nonlinear processing. If the low end changes too much, revisit that main path and global balance. More return is useful only while the line's pitch and rhythm remain stable in the arrangement.

A creative use: make colour a performed layer

On a sustained synth or guitar texture, choose a restrained main valve tone and automate the focused return's contribution during selected phrases. A gradual increase can make a held part become more textured without changing its MIDI or audio notes. Keep the Focus choice steady while auditioning the gesture.

Auto Gain offers Off, Live, Learn and Hold. Use those choices deliberately when comparing or printing a moving treatment. A level-learning state and a held compensation state serve different purposes; avoid interpreting changing compensation as part of the intended musical swell.

Check what the interaction is costing

After the tone works, compare the entire phrase at a fair level and include any sparse section where the effect is exposed. Listen for softened attacks, changing sustain or a stereo centre that no longer feels appropriate for the source.

Keep a clear description of the chosen topology, main valve setting and extra return. Valence becomes easier to use creatively when those three decisions have distinct jobs rather than being treated as several versions of the same saturation amount.
