Beat-synced FX? Get inspiration from Roger Linns Adrenalinn pedal!

#1

Hi!
Before discovering the MOD ecosystem I had a lot of fun with the Roger Linns Adrenalinn 3 pedal, Which was one of the first midi beat sync pedals for guitar.

Since most of these FX are possible to recreate on the MOD I felt like sharing some tips and tricks from the preset descriptions in the pedals manual. Adrenalinn 3 presets As they are very well described in detail.

Big thanks to Roger Linn and his great contributions to music, and to the MOD-team for pushing sound technology further and making it available for everyone! :heart:

Hi! The document is quite a bit to read through. The only plugin i have seen which does audio effects synchronized with the host tempo is Bollie Delay. However, unless you are doing a song who bpm varies, then you only need to do a bit of maths to get the right numbers. I asked copilot about that and this is what it wrote back to my query:

write a short explanation about the relationship between hz, bpm and msecs in relation to musical beats. For instance if I wanted to make a vibrato or tremelo whose fluctuations work well with a 120bpm beat, what hz setting should I use on the pedal

Core Concepts

:musical_note: BPM (Beats Per Minute)

  • Tells you how many beats occur in one minute.
  • 120 BPM means 2 beats per second.

:zap: Hz (Hertz)

  • Measures cycles per second.
  • A tremolo at 2 Hz means the volume modulates twice per second.

:stopwatch: Milliseconds

  • 1 second = 1000 ms.
  • A beat at 120 BPM lasts 500 ms (because 60,000 ms / 120 BPM = 500 ms per beat).

:repeat: How They Relate

To sync an effect with the beat, you want the modulation frequency (in Hz) to match a musically meaningful subdivision of the beat.

:dart: Example: 120 BPM

  • 1 beat = 500 ms
  • So:
    • 2 Hz = 1 modulation every 500 ms → 1 per beat
    • 4 Hz = 1 modulation every 250 ms → 2 per beat
    • 0.5 Hz = 1 modulation every 2 beats (1000 ms)

:control_knobs: What Hz Should I Use?

If you want your vibrato or tremolo to feel rhythmically aligned with 120 BPM, try:

Hz Subdivision Description
2 Hz 1 per beat Strong sync with beat
4 Hz 2 per beat Eighth-note feel
6 Hz Triplet feel Jazzy or swung
8 Hz 16th-note feel Fast modulation
0.5 Hz Every 2 beats Slow pulse

:white_check_mark: Recommended for 120 BPM

  • 2 Hz is a great starting point — it aligns perfectly with the beat.
  • 4 Hz works well for a faster, more energetic feel.

What ?!?
Every potentiometers in with ms or Hz can be assigned with the host tempo.
On my main pedalboard I have :

  • a tremolo
  • a CV plugin
  • a delay (the @Jacube one)

Really? I didnt know you could do that! So when you change the host tempo (e.g from 120bpm to 130bpm) the hz settings on the pedals automatically change with it?

Yes I posted it because everything can be done with MOD. I espcially had the new dm-Seq sequencer http://builder.mod.audio/install/b77siz3jin mind and all the possibilities it opens up!
