"Litmus Test - def: any kind of indicator used to classify something either favourably or unfavourably"

Over many years of analysing the timing performance of different musical sequencing devices we rely on a very simple test that gives an accurate indication of just how well they keep time.

Take any sequencing device - in a sampler use a tight edited fast transient sound like a rim shot - look at it closely on an editor software application to make sure the start time is tight. On a ROM Player or sequencer with built-in sounds - select a similarly tight percussive sound or patch.

Make certain any sample output or patch VCA/EG settings are set to absolute zero/fastest possible attack time.

Sequence a simple two bar pattern at exactly 120 BPM with hard quantised Sixteenth Notes playing only your test sample.

Now play the pattern and record the audio output into any reasonable audio recording software application at 48 kHz for a few bars - Soundforge, Wavelab etc.

[It is not necessary to use a lab oscilloscope for this type of testing. We are interested primarily in analysing timing discrepancies that you can hear. Measuring rhythmic precision down to the individual sample at 48 kHz (20 microseconds) is more than accurate enough.]

Open up the waveform of your recording. Make sure your editor is set to view and edit your waveform in samples rather than absolute time.

Zoom right in on the very front of a waveform (any of them will do) and place a marker - do it at the absolute maximum magnification on screen so you are certain the marker is where the waveform begins.

Now zoom back out and locate the very next waveform in the recording and again, zoom all the way back in and place another marker at the very start of this one too. Repeat this for at least 8 of your recorded 'clicks' in the recording - 16 is better if you have the patience.

Now 'select' the block between the first two markers - usually clicking in the area with the mouse does the job. Somewhere on screen the number of actual samples between your two markers will be indicated.

Write this number down. Repeat this for each 'block' between all markers you have placed.

At 120 BPM - a perfect Sixteenth Note interval recorded at 48 kHz is exactly 6000 samples in length.

The amount your Sixteenth Note intervals vary will indicate how tight your sequencer or drum machine really is. The bigger the variation, the sloppier the timing.

Two things obviously affect this measurement - the real tempo (as opposed to what it tells you on the screen) and jitter (tempo fluctuations). What is critical is the amount of variation you find in your measurements. If your results vary by more than 50 samples then the device's ability to keep tight rhythmic time is questionable. Remember that our test is very easy on the hardware and software resources - a single track of well spaced events. There are no polyphony or multitimbral excuses to hide behind.

Sequencer Tempo Jitter/Event Slop has two primary causes - Clock Jitter (where the clock driving the internal sequencer or slave device is a bit rough) and Internal Event Trigger Lag (where a devices ability to correctly trigger an event referenced to the tempo grid/clock position is compromised in someway leading to push-pull within the device itself).

The net timing performance stability in any sequencing system is a combination of both these factors.

Keep in mind also that these test results are the very best your box or software application can produce. Under normal usage you will usually find things get much worse.

Published hardware and software specifications in owner's manuals, on-line and in the glossy brochures and print media focus almost exclusively on the myriad of bells and whistles on offer. The aim being of course to tempt and tease in a bigger, faster, wider, louder, and 'newer is better' display of spec-superiority - polyphony, memory, number of patches, high sample rates, track count, plug-in support, data I/O speed, CD Burning etc.

What they never publish is timing performance.

You can spend a fortune on furnishings and wallpaper but a house is only as good as the foundation it is built on and in sequencing the foundation is the tempo-clock.

[On a recent forum regarding sequencer timing stability the audio/DAW method of timing measurement as outlined here was strongly critisised by some as being too inaccurate to be considered meaningful when measuring tempo jitter in sequencers. For those of you reading this with similar views I thought it important to quote a direct reply from a senior member of the design/R&D team involved with the product in question: ' There is nothing wrong with your method of measuring the timing jitter, any fully working sound card will do.']

Time is the core foundation on which music is created because what turns random sound into music is how the sounds are played or replayed over time.

There is a common misconception that certain sequencers and drum machines have a magic ‘groove’ or feel built right into them. After many years of testing and experimentation our own belief is that there is no 'magic' beat box feel - vintage or contemporary. What gives any rhythmic pattern 'feel' is how we anticipate where the sounds fall in time and, because every individual hears subjectively, it makes practical analysis and criticism of timing performance in sequencers very difficult.

Adding any random element to step/event placement in any sequencing device or software application does not create feel. All this does is blur the edges. 

The exact opposite applies when deliberate push-pull placement of steps and events against a strict, quantised tempo-grid is used to customise rhythmic feel - pushed hats, late snares and of course added amounts of shuffle/swing.



Discussions about timing precision in music always invoke passionate debate and there are many who see any quest for tighter timing performance as an obsessive desire for extreme rigidity and control. The assertion being that this is a very negative characteristic and that ‘going with the flow’ and accepting some element of ‘human-feel’ is a far more musically appealing way to be.

Rigidity has negative connotations for most musicians but a desire for precision and consistency in sequencing is not about rigidity or stiffness at all. Quite the reverse in fact.

Rhythmic feel fundamentally relies on the strict principle that if a snare is deliberately placed 5 ticks late it must always sound 5 ticks late to faithfully maintain the groove. The potential feel in any rhythm becomes less focused when the snares fall 3 ticks late sometimes and 7 ticks late other times in a pattern or loop when this timing variation is of a random nature.

It is very important not to confuse random timing errors with any concept of creative groove and/or the deliberate application of 'human' feel. It is not feel or creative and certainly not deliberate in any sense because the timing variation is random and has nothing to do with the user at all.

It is simply a combination of software and hardware not doing its job well.

As we get around to it we will list here measurements on various boxes and software sequencing applications. All tests as specified above - 120 BPM recorded at 48 kHz into Soundforge 8 or Soundforge 9. The group of measured consecutive sixteenth note intervals will be listed in samples along with a maximum variance between any two.

On first inspection it may seem that measuring the error margin away from the theoretical 'perfect' grid value of 6000 is a more accurate way to look at these numbers, however, human perception of rhythmic feel is how our brain interprets the length of time BETWEEN consecutive rhythmic events. This is why the push-pull timing of consecutive events is the most significant set of numbers to consider when looking at sequencer timing stability.

Date of test and current Operating System is listed. Obviously a change of OS may mean a change in test results. Equipment listed is in no order of personal preference.

Feel free to email us if your own testing provides a different set of numbers.

Remember that this is a highly biased rating system based on one feature only. Important as timing performance is, there are many other aspects to software and hardware sequencers that contribute their overall worth as creative tools.

Our genuine wish is that the designers and manufacturers of our current and future music machines start placing timing performance at the very top of the priority list when it comes to features and OS updates.

The motivation for the Litmus testing is not to cause any individuals or organisations grief but simply to provide reliable timing information to those who wish to know.

The CR-78 uses a variable analogue oscillator for internal tempo control and 120 BPM is a guide only - the important data is the variance of the values around the mean/average. The front Rotary Tempo Control knob is touchy which means precise Tempo-Lock is not possible without a stable external clock source.

Some interesting observations particular to the Roland TR-606

If you look closely at the reported values you can see that in almost all cases the 16ths intervals actually 'swing' with very tight precision. Whatever processor code is causing the TR-606 to 'push and pull' is very specific. To show this all we do is add pairs of 16th intervals together:-

Number of samples [48 kHz] between consecutive 8th Note Intervals:
12206/ 12206/ 12206/ 12207/ 12206/ 12207/ 12206/ 12104

Maximum variation between any two consecutive 8th Note intervals:
103 Samples [2.15ms]

Aside from the odd pair our 8th Note intervals are close to being sample accurate. These values go a long way towards proving that the Roland TR-606 may be the only Drum Machine in existence with 16th Swing built into the box except for one very critical problem. The 'push-pull' timing error between 16ths is not always in the right spot. We hear rhythmic swing when each and every second timing interval is slightly shorter than the one preceding it. If the pairs 'flip' so that a second timing interval is longer than the one that precedes it then the swing is reversed and the rhythmic feel is lost. This is what happens with the TR-606. More problematic is the fact that the timing 'flip' changes with each restart and, once running, the timing 'flips' are random.

The following numbers report 16th intervals under sample accurate Din-Sync:-

* Cold Start 1 (Swing Position is Reversed)

5947/ 6050/ 5946/ 6050/ 5948/ 6049

* Cold Start 2 (Correct Swing Position)

6049/ 5947/ 6050/ 5947/ 6050/ 5947

* Cold Start 3 (Swing Position is Reversed)

5947/ 6050/ 5948/ 6051/ 5947/ 6050

* Cold Start 4 (Swing Position is Reversed)

Before Midi there was electricity. There was no aftertouch or sysex or active sensing. It was simply on and off and sometimes how much. Electrical pulses travel close to light speed and processing was just as fast.

Most vintage synthesizers, sequencers and drum modules used voltage triggers and gates to fire Voices, Envelope Generators and VCAs. With the recent resurgence in analogue modular synthesis there are many new devices available that avoid Midi in favour of voltage triggering.

Depending on the design, different Envelope Generators and VCAs will vary in how fast they respond to voltage triggers and gates. Sometimes a Microprocessor is used and this will have some effect on latency (trigger response-lag) and precision (trigger response jitter).

Many analogue and EPROM/Sample based drum modules use triggers to fire their voices too.

The tests below show how fast different devices respond to external voltage triggers and gates and the stability of their internal tempo generation.

There are times when you need to take a single stream of Midi Clock and distribute it to multiple devices. Although many Midi instruments provide a dedicated Midi Thru port it is generally accepted that the practice of 'Daisy-Chaining' is best avoided in favour of using dedicated Midi Thru Distribution hardware.

There are also situations where you may need to take a single stream of Midi Clock and merge this with Midi Note data from another source in order to get both combined into a devices single Midi Input.

There are numerous Midi Thru and Midi Merge hardware devices in circulation and they all use different internal hardware and software designs to achieve Midi Merging and Midi Cloning at their outputs.

The tests below show the outgoing Midi Clock tempo stability produced by various Midi Merge and Midi Thru devices.

At 120 BPM - a perfect Midi Clock interval recorded at 48 kHz is exactly 1000 samples in length.
