Modular Concepts: Basic Modulations

This tutorial explores basic control signals, a core building block of patching. Starting from the default Poly Grid patch, we explore using envelopes and LFOs to manipulate pitch, both individually and together. With an understanding of how these generators work, you could apply them successfully to any type of parameter. As in any modular environment, modulations are what make any patch in The Grid dynamic and alive.

0:13 - Default patch at a glance
1:10 - Two basic modulation signals
2:27 - Using a pitch envelope
4:09 - "Attenuator test" when using notes
5:06 - Pitch LFO for trill
6:05 - Pitch LFO for vibrato (and glissando)
8:00 - Joining streams: vibrato that fades in

Modular Concepts: Phase, a Matter of Timing

This tutorial explores phase for driving step sequencers and animating sound. We start by looking at Bitwig Studio's default tempo-locked behavior and then manipulate phase signals to create interesting relationships. Phase is a uniquely powerful idea, which is why it is central to The Grid and worth getting comfortable with.

0:28 - Pitch, timbre, loudness… and phase
1:19 - Driving the DAW
2:00 - Trigger-driven model via Ø Counter
2:55 - Phase pre-cords make things moving
3:34 - A few phase processors
5:58 - Manipulating a synth sound
7:06 - Going polyphonic
7:38 - Breaking down a phase signal
9:02 - An LFO to drive phase
10:48 - Scaling phase with each note's velocity



Modular Concepts: Musical Maths

While math is everywhere in sound synthesis, it doesn't always ask for attention. This tutorial looks at three examples: making a patch velocity-sensitive, seeing how low-pass filters relate to amplitude, and using comparators to make a looping envelope. By lifting the veil on a few simple ideas, take The Grid (and any modular environment) to a new level.

0:08 - Math: it's all around us
1:10 - Logical functions too
2:05 - Task 1: Velocity as an amplitude control
3:24 - Level Scaler for range
4:03 - Using decibels is nicer
4:32 - Task 2: What is a low-pass filter?
5:45 - LPF makes things slow…
6:22 - …now we can slow other signals
7:20 - Lag is a filter set in time
7:55 - Task 3: building a looping envelope
8:43 - Talk thru how this should work
9:13 - When the envelope reaches zero…
9:48 - …AND the note is still held, retriever
10:39 - Details, like routing feedback…
11:10 - …merge the triggers with OR…
11:57 - …and short logic signals help OR work
12:50 - It loops! Go crazy!
