Vocal Delay Ducking

The normal thing to treat a dry vocal is to put reverb and delay on it. But that could make the vocal a bit muddy.

To keep it in-your-face and conserve the clarity of the vocal, while still having an effect to make it sound bigger, try ducking the volume of the delays whenever the dry vocal is active. To do so, side-chain the delay bus to the lead vocal track.

For example, use a delay device on a return bus and put a quarter note delay with low feedback, and send it to the vocal track with a little less volume. On the same bus, put a compressor and select the vocal track as the side-chain source. Set it up as you like, perhaps bring down the wet-parameter some.

You can also try the same thing with a reverb.


Create a Shimmer Reverb

Shimmer is a feedback-reverb-pitch-shift-effect made popular by Brian Eno and Daniel Lanois. The idea is to feed a reverb to a pitch shifter and back again. Each delay repetition gets shifted one octave up. In this case I’m using Ableton Live with stock effects, the Reverb and Grain Delay where the signal gets delayed and pitch shifted. You can use these guidelines in different environments (hardware/software) but here’s how I do it:

  1. Insert two Return Tracks and put a Reverb on A.
  2. Turn off Input Processing Hi Cut, set Global Quality to High, turn off Diffusion Network High, a fairly long Decay Time and turn the Dry/Wet to 100 %.
  3. Enable Send B on the Return Track A and set it to max.
  4. Use the Grain Delay on Return Track B.
  5. Set Frequency to 1.00 Hz and Pitch to 12.0.
  6. Enable Send A on the Return Track B and set it to max.
  7. Dial Send A of the Track with the signal source that you what to shimmer.

Also try to bring in Send B on the signal. And play with the Size and Diffuse controls of the Reverb.

Split Frequency, Split

I’ve written about the perks of putting side-chain compression on only the low frequencies of a bass earlier.

To do so, three copies of the sound are needed. Or, as this post will show, you could split the frequency into three bands (high, mid and low). By doing this, it is possible to apply different signal processing on each band.

Now I usually try to write about music production on a more abstract level, and not about a specific DAW or instrument, but this time I going to illustrate with Ableton Live on Mac. The theory is the same though, you just need to figure out how it works in your particular environment.

So I’m using the stock effect Multiband Dynamics to split frequency. The device has noticeable affect and coloration on the signal, even when the intensity amount if set to zero, but it should be transparent enough for now.

  1. Drop a Multiband Dynamics in the Device View.
  2. Set the Amount control to 0.0 % to neutralize compression or gain adjustments to the signal.
  3. Group the Multiband Dynamics in an Audio Effect Rack (select the device and press CMD + G).
  4. Show the Chain List of the rack.
  5. Dictate the crossover points on High and Low (the Mid consists of what is left in between, so remember to also change the crossover points in the mid chain if you make adjustments on the others), e.g. set the bottom of the frequency range of the high band to 1.00 kHz.
  6. Duplicate the selected chain two times.
  7. Rename all of the chains High, Mid and Low, from top to bottom.
  8. Solo each band respectively on the Split Freq, i.e. solo Low on the low chain.

Now process each band individually. Use a Utility device on the low chain and set Width to 0.0 % to direct the low frequencies to mono. Also, on this band, set up a side-chain compression triggered by the kick drum. Try a stereo widening effect and some reverb on the mid chain. And perhaps a little saturation to add some crunch on the high chain, I dunno, it’s up to you.

Bedroom Studio Tips Revisited

Three years ago I posted a list of some music production methods and tips on my blog that still gets some attention. Now, here’s some other good read (I hope).

Moreover, you really should check out the most popular post on this blog about the best tips on music production that I can think of.

Entering the Matrix

I got a reasonably priced Oberheim Matrix-1000, originally released 1987. It’s a polyphonic synth with six voices, two DCOs per voice, fully analog signal path and extensive modulation routing options – and its sound is beautiful.

But yeah, it’s a rack module and without editing options via the front panel, and it has a thousand presets and only 200 of them are editable remotely via MIDI.

The trouble with this particular item was that the fifth voice chip was broken (which I found out after buying). Moreover, the firmware running the synth was slow and contained bugs.

Fortunately someone on the internet has updated the code and they have made it available on a EPROM chip, so I ordered that. I also found a replacement voice chip and got that as well. Installing the new firmware and voice chip into the old machine was easy enough – the chips are just sitting in sockets. The voice chips counts from right to left (one to six) and are marked U101-U601.


About Recursive Modulation

Here’s something for you synth programmers to try out: Modulate certain aspects of an envelope with itself.

For example, set the modulation destination of the filter envelope to affect its own parameter, such as its (linear) attack or decay time, by a positive or negative amount. This should render a concave or convex shape, respectively.

This effect is referred to as recursive modulation.

Now try to set filter envelope attack to 32, and envelope amount to 48. Then go to the modulation matrix and select the filter envelope as source, and modulate the destination filter envelope attack by 48.

It’s also possible to use this method on a LFO. Modulating its own level will also affect the shape of the LFO. And by modulate its own rate, will affect both the overall rate and the shape.

About Effects Chain Order

First off, there’s really no correct order. It’s all about preference, what you want to achieve and context. Although some effects do seem to work better in certain places of the signal path than in others. Still, feel free to experiment.

Inserts and Send Effects

Effects are chained in either series or parallel. For parallel processing, use send effects to process a copy of a signal (without affecting the original). Use auxiliary sends for time-based effects, such as reverb and delay.

No rules, but in most situations it makes more sense, and saves processing power and setup time, if for example reverb and delay are shared between all channels, rather than inserting a new instance of each effect in an insert slot on each channel.

Use insert effects to change the signal completely, e.g. dynamic processors like compressors, expanders, noise gates, transient shapers.

In terms of signal flow, the channel insert connections usually come before the channel EQ, fader and pan.

Daisy Chain Effects

It is possible to daisy chained effects into the signal path. The order of the effects determines the sound and have different impacts. Here’s a suggestion:

  1. Noise gate
  2. Subtractive EQ
  3. Dynamics (compressors, limiters, expanders)
  4. Gain (distortion, saturation)
  5. General EQ
  6. Time-based modulation (chorus, flanger, phaser)
  7. Pure time-based (delay, reverb)

To clean up the signal, put the gate first, and it will work better with a wider dynamic range (than for example after a compressor).

Then use an EQ to cut away the unwanted frequencies; do this to avoid enhancing them with later effects. (Also maybe roll off frequencies below 30 Hz.)

Then place a compressor to adjust the dynamics of the signal.

After that, put on some overdrive boost or tape saturation effect. Also, such effects can work well in the beginning of the chain – as part of the initial sound – due to the harmonics generated by a distortion device, which bring richness to the effects that follow.

After gain effect, EQ to shape the tonal balance, but be careful when boosting.

At the end of the chain, modulation effects are usually placed after gain-related effects and before pure time-based effects.

Pure time-based effects such as delay and reverb usually come last in the signal chain.

The Mastering Chain

This post is mainly covering effects chain for channels and buses, but when entering the mastering stage, a conventional order of the mastering chain is:

  1. EQ
  2. Dynamics
  3. Post EQ
  4. Harmonic exciter
  5. Stereo imaging
  6. Loudness maximizer

Minimal Bedroom Studio

As a consequence of scaling down my home studio, I sold two audio interfaces, Apogee Duet for iPad & Mac and Propellerhead Balance, to acquire an Apogee Quartet instead. (Yes I was checking out the newer Element 46 and even if the Element series audio quality and mic pre technology are a step above, the Quartet’s specifications are good enough for me, and more importantly I wanted/needed 8 outputs and a convenient front panel control.)

I decided for a 4-channel audio interface because I didn’t need 20+ hardware synths and drum machines up and running all the time. All that stuff took up too much space and I didn’t really use them. They were connected to a mixer – functioning more or less as a patchbay – and now that mixer is redundant. Remember, limitations drive creativity and all.

With the current setup, I’m able to insert outboard gear, not only to use Minitaur and Mopho as analog instruments, but also as signal processors/external filters. That is, with a little bit of routing in Ableton Live, I can send hardware and softsynths to the Moog ladder and Curtis low-pass filters.

Right now I got three analog monosynths (Minitaur, Mopho and SH-101) connected, and Analog Keys operating as an analog polysynth, master keyboard, sequencer and MIDI to CV converter. I can record all synths mentioned on separate tracks at once.

The plan is to switch gear depending on the project. It’s a clean, minimal setup which seems to suit me.

Recently, most time has been spent tweaking the setup, experiment with the gear, and programming and sound designing on the synths. I haven’t made any real compositions for a while though.

Next up could be a cassette tape recorder (to be able to make some lo-fi tape compression/saturation). And I think I’ll get the Strymon Deco pedal and put it in an effect signal chain.

Downscale for Creativity

At one point I had all gear connected, like this. That’s over 20 hardware synths and drum machines, integrated in a working and sort of intuitive ecosystem. The idea was to be ready and not having to unpack and reconnect shit, which could be time-consuming and kill inspiration in the meanwhile.

But, I tried this setup for a month, and for me it didn’t work that well. Every time I saw the pile of stuff I suffered a little from some kind of performance anxiety, I froze. It was like all this premium gear was looking at me and saying, “we’re just perfect and you got all possibilities in the world man, why can’t you produce better music? You’re not worthy.”

In spite of its purpose, the setup with all gear mounted and routed had become counterproductive. Truth is, I always worked best with constraints, regarding concept or gear, and to some extent, even budget. For me limitations do drive creativity.

Therefore I disassemble the gigantic keyboard stand and everything on it. (Also, I live in a relative small flat and a home studio like this takes more space that I can afford.) I haven’t yet worked out a storage system for all gear, but I think I put (hide) them in some drawers.

The new idea is to only have a master keyboard/MIDI controller, an audio interface, a mixer, a pair of studio monitors connected to a DAW, and then temporarily plug in the hardware I want to use for a certain project. Right now I’m working on three tracks and there are only four synths on my desk: Elektron Analog Keys, Moog Minitaur, Roland SH-101 and Casio CZ-101.
