Sample Aid


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 sampling anomalies.

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 velocities:-
  • 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 them ;)

Using Sample Aid with EMU Ultra samplers - step-by-step guide

EMU E4B FAT-format - example samples (approx 65MB) - all zipped files are held on the storage site. If there are problems downloading, check your computer's access or contact me via email address at bottom of this page.
The samples are from a test session using example Ex4 in the above step-by-step guide, sampling a Dotcom modular synth on an EMU Ultra.
19 velocity bands were used, giving a total of 399 samples, using the following settings:-

Example Sample Aid settings for large multisample session 


  • Run/double-click the program (see notes above) installation file and follow the prompts
  • Repeat for the documentation installation file, using the same destination locations as the main program.
    (administrator privileges are required)
Windows may prompt for permission to install using various messages...
  • If you see: Windows protected your PC - Windows SmartScreen prevented an unrecognised application from starting...
    Click 'More Info' to reveal a button marked 'Run anyway' and click that.
  • If you see: User Account Control - Do you want to allow the following program from an unknown publisher to make changes to this computer?
    Click Yes.
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.

Please contact me if you have any problems.


Use the standard uninstall/remove process in Windows Control Panel.
Administrator privileges are required, so you may need to acknowledge User Account Control prompts as shown above and/or logon as an admin user first.
