This tool generates a sequence of MIDI notes with a specified range of
pitch & velocity steps. The sequence can be single-stepped, played
once or played continuously, providing an accurate & repeatable source
of MIDI notes. The intended uses are for triggering a sound source for
sampling, and for auditioning or comparing sample-based synths for
The audition sequence can be used to drive any sample-based sound module
with a set of pitch/velocity variations while listening for sampling
anomalies, e.g. if insufficient notes have been sampled, there may be
audible jumps in timbre between sampled and interpolated notes. Similarly
for samples taken at different velocities. This sequence runs faster than
the sampling sequence so you can scan through large ranges quickly, and
values can be adjusted on-the-fly to home in on any anomalies.

The sampling sequence can be used to drive a target sound source with an
ordered set of pitch/velocity combinations for sampling, e.g. for
increasing the polyphony of a hardware or software synth. This sequence
runs slower than the audition sequence to allow time to arm and place each
sample as reqd.

The tool offers several advantages over manual triggering from a keyboard,
especially if there are lots of samples or you need to sample at different
- The length and velocity of all notes are accurate and repeatable,
allowing you to create more consistent samples when sampling, or spot
anomalies more easily when auditioning.
- Sampling can be tedious and error-prone, so playing a pre-generated
sequence of notes allows you to concentrate on arming & placing
each sample as it arrives automatically; some samplers may even
automate this part of the process. You can pause the sequence at any
time to adjust values, or simply adjust values on-the-fly.
- Even if you donít want full automation, you can still semi-automate
the process using the manual single-step function; the pitch &
velocity for each sample are still generated automatically, allowing
you to concentrate on the sampler.
- The built-in estimator helps you decide your sampling strategy
before you start by showing the relationship between samples, memory,
time and effort.
Minimum system requirements
Windows XP and later.
Tested on XP, Vista, & Windows 7.
Note the Sample Aid tool lives inside Sequetron
so it is not
a separate program. You install Sample Aid by
downloading and installing Sequetron LE, then use Sequetron's menus to
start the Sample Aid tool - exact details are in the Installing section
below. Sample Aid is fully functional
in both the LE and Full
versions of Sequetron. The LE version is free, but if you pass it on
please keep the package intact.
Of course, once you've captured your samples using Sample Aid, Sequetron
is at hand to drive the sampler and help create something amazing with

follow the prompts
- Repeat for the documentation installation file, using the same
destination locations as the main program.

Windows may prompt for permission to install using various messages...
- If you see: Windows protected your PC - Windows SmartScreen

Once installed, Sequetron can be started via Start, Programs etc.
The following steps are also shown at the start of this video
- When started for the first time, Sequetron will be in novice mode -
you can leave it like this or toggle it off by clicking Sequetron's
menu 'Config, Novice mode' - it makes no difference to Sample Aid.
- Click menu 'Settings, Ports/MIDI' and allocate your MIDI output
device(s), click Done to return to the main screen.
- Click Run in the Control section of the main screen - this starts
Sequetron's timing clocks which are required by Sample Aid.
- Click Save in the Control section of the main screen to save your
MIDI settings for next time. When you next start Sequetron it will be
in Run mode so you can skip this and all previous steps.
- Click menu 'Tools, Sample Aid' to start Sample Aid running - you can
drag Sequetron's windows out of the way if necessary as you don't need
to do anything else with it. If you want to reconfigure the MIDI
ports, click Stop in the Control section of the main screen, then
click 'Settings, Ports/MIDI' as before, Save, then Run.
