  • 1. USING REASON FOR LIVE P.A. By Lionel Zivan S. Valdellon [acid42]
  • 2. About this guide • Originally created in 2005 • At the time, only Reason 2.5 • Most principles are still valid however 2
  • 3. What is Reason? • Sequencer • Virtual synth racks • Song info: mainly MIDI • Small song file sizes 3
  • 4. What do you need? • Laptop • Good soundcard • MIDI controller • Good cables An example of a live setup I used in 2002. 4
  • 5. #1. Use Reason as a sequencer
  • 6. #1. Use Reason as a sequencer [A] Go Linear. For ultimate control. – Sequence entire songs. – Play them from start to finish. – Problem: Not much variety. 6
  • 7. Add variety by: A) Playing with loop points – Loop entire song, or – Loop certain sections by dragging loop Left and loop Right markers and clicking “Loop On.” 7
  • 8. TIP: Changing loop points 1. Manually dragging the loop indicators with your mouse (HELL!!!) 2. Typing in the loop start and end measures in the L and R boxes at bottom right of transport panel, and then pressing ENTER. (PRONE TO ERROR!!!!) NOTE: Wait for box to appear before typing the new measure number and pressing ENTER. I’ve stopped my set numerous times by pressing ENTER without looking. 8
  • 9. TIP: Changing loop points 3. Positioning your mouse over the measure numbers and then use these shortcuts – CTRL + mouse click (for start loop point) – ALT + mouse click (for end loop point) 9
  • 10. Add variety by: B) Playing live keyboard on top – Live playing adds energy, spontaneity – Hence the need for a USB controller of some sort 10
  • 11. Add variety by: C) Randomly replacing rhythm patterns – Introduce a Dr.Rex module – Load a random REX pattern – Mute your regular rhythm tracks – See what happens next. Sometimes accidents produce great results. 11
  • 12. #1. Use Reason as a sequencer [B] Play short repeating grooves. – Pre-sequence short phrases (think 16, 32, 64 measures) – Play with loop points. Here is an example of a track I made with only two sections, each 16 bars in length. Toggling between sections is the tricky part. 12
  • 13. #1. Use Reason as a sequencer [C] Build it from scratch • Most radical method. Most stressful. • Start with basic drum loop • Build parts as you go • Spontaneity results in either pure genius or massive error 13
  • 14. #1. Use Reason as a sequencer [D] Mix pre-made songs like a DJ. – You can have several songs open at a time (watch your CPU) – Match the BPMs of your songs (Beat matching) 14
  • 15. TIP: Beat matching 1. Latency check: • Make sure your latency settings are optimized, otherwise impossible to match up beats. • Adjust buffer size till no dropouts 15
  • 16. TIP: Beat matching 2. Visual Beat-matching: • Watch bottom of transport panel (position meter) • Get the beat numbers to match. Here are 2 songs with the beat counters next to each other for easier monitoring. 16
  • 17. TIP: Beat matching 3. Layered parts: Bonus tip • Set 2nd song to loop for 8 bars or so • Use 2nd song's rhythms as a layer over the 1st song's melodic parts, or vice versa. 17
  • 18. TIP: Beat matching 3. Layered parts: Bonus tip Here, the first song’s kick drum is soloed while the 2nd track is playing. 18
  • 19. #2. Use Reason as a tone module
  • 20. #2. Use Reason as a tone module • Harness Reason's power with a MIDI or USB keyboard controller • Control just one tone module at a time, (default) • Or layer several instruments for a fat, lush sound 20
  • 21. TIP: Layering synths Taken from 1. Go to Preferences >MIDI. Ensure the correct port is linked to your keyboard. 21
  • 22. TIP: Layering synths 2. Go to “Advanced MIDI" Select the same port for both Bus A and B (and C and D, if you want). 22
  • 23. TIP: Layering synths 3. Check which MIDI channel your keyboard is set to send MIDI messages from (usually channel 1). 23
  • 24. TIP: Layering synths 4. In your MIDI interface (top of Reason rack), select bus A and from the dropdown arrow beside channel 1, select the instrument you want to layer (say a Subtractor 1). 24
  • 25. TIP: Layering synths 5. At Bus B, go to channel 1 and select the next instrument you want to layer (say, a Pad ). • Repeat for as many as 4 busses or layers. Now all MIDI info from your keyboard is routed through the busses and through a dedicated channel 1 path to all instruments on that channel. 25
  • 26. #3. Changing parameters
  • 27. #3. Changing parameters • Beauty of Live P.A.= full control over all your sound parameters • You have built-in effects units to control your sound. • Effects, filters, envelopes, panning, EQ, anything with a knob or slider! 27
  • 28. #3. Changing parameters [A] TWEAK EFFECTS • Easiest way to "play" with your sound • Effects in Reason are built-in, thus stable • Play around. Experiment. 28
  • 29. #3. Changing parameters [B] ALTER NOTES • Highlight some sequenced notes, right-click, and pick Change Events> Alter Notes. Choose % • Randomly changes note position. New melodies and rhythms from old. 29
  • 30. #3. Changing parameters [C] TWEAK THOSE KNOBS • Parameters such as: filter, resonance, attack, decay, sustain, release. • Find out what each can do to a sound. And then play with your sound. • Some examples… 30
  • 31. TIP: Knobs and Filters Frequency sweeps • Set the Matrix going with a cool rhythm pattern on a Subtractor • Grab the filter FREQUENCY knobs as the pattern plays. • Min: gurgle Max: wide full sound 31
  • 32. TIP: Knobs and Filters Envelope decay variations • Get a pattern going on a Subtractor • Grab DECAY slider. (“D”) • Min: notes are cut short, Max: wall of echoing sound. 32
  • 33. TIP: Knobs and Filters Resonance boost • Grab RESONANCE slider (“R”) • High resonance w/ short decay: quick rhythmic blips • Low resonance: filter will woof. • Turn down resonance for a more even sound. 33
  • 34. TIP: Knobs and Filters Oscillator sync sweeps • Subtractor:2 oscillators • Lower the pitch of less dominant oscillator by a couple of octaves: metallic sweep of the overtones. 34
  • 35. TIP: Knobs and Filters Waveform crossfades • Set up an oscillator tuned an octave or two below the first • Fade it in and out with Mix knob. If your synth has a Distortion effect, tune the second oscillator to some other interval (a fifth above the first oscillator, for instance) and bring it in with a knob for a great thickening of the tone. 35
  • 36. #4. Personalized settings
  • 37. #4. Personalized settings [A] KEYBOARD MAPPING • Allows you to activate something without using mouse. • Options > Edit Keyboard Remote • Assign QWERTY keys to buttons you’ll need • Personally, I have set it up so that each mixer channel mute button, each Redrum pattern and each Matrix pattern is mapped to a QWERTY key. 37
  • 38. #4. Personalized [A] KEYBOARD MAPPING settings ACID42's Keyboard Map: Mixer Channel mute buttons: 1: Q. 2: W. 3: E 4: R 5: T 6: Y 7: U 8: I 9: O 10: P Redrum Pattern enable buttons: 1, 2, 3, 4, 5, 6, 7, 8 Redrum Bank A enable: shift + 1 Redrum Bank B enable: shift + 2 Redrum Bank C enable: shift + 3 Redrum Bank D enable: shift + 4 Matrix Pattern enable buttons: 1: A 2:S 3: D 4: F 5: G 6: H 7: J 8: K Matrix Bank A enable: shift + A Matrix Bank B enable: shift + S Matrix Bank C enable: shift + D Matrix Bank D enable: shift + F 38
  • 39. #4. Personalized settings [B] YOUR OWN DEFAULT SONG • Save your keyboard mappings and all shortcuts as your "Default Song.rns" • Start every new song with "Default Song.rns" 39
  • 40. #4. Personalized settings [C] SONG INFO = USEFUL INFO • Pressing CTRL+I > Song Information window • Place useful info for your performance: a.) Chords (in “Text in window title”) b.) List relevant measure numbers where sections change (in “Text in window title”) c.) Lyrics even! (in “More information”) 40
  • 41. #4. Personalized settings [D] MAKE FILENAMES USEFUL • Make it is easy to find songs which can be beat-matched. • Put BPM before song title. • Put genre after BPM. 41
