Getting Started Instructions
From the downloads page select the software for your system. Once downloaded follow the onscreen instructions to complete the install of both Xtractor and Analyser.
All you need in order to learn with Gigajam is an instrument and your computer. The two do not have to be connected. Xtractor can be used to play along with and the course can be read and worked through step by step.
However, if you want to use the recording features and feedback of Xtractor/Analyser then you will need a MIDI instrument and a way to connect your instrument to your computer.
If you do not have MIDI then just jump to the Beginning to Learn section.
Nowadays, many Casio keyboards have built in USB MIDI, if this is correct in your case then all you need do is install the drivers and connect a standard USB cable from your keyboard to your computer.
If you don't have USB MIDI then you may still have MIDI capability, look for sockets like these on the back.
MIDI IN and OUT sockets.
Often, you will also see this logo on your keyboard somewhere.

If you have MIDI sockets but no USB on the keyboard then you'll need to buy and setup a MIDI interface.
Modern MIDI interfaces tend to be USB based devices, the usually look a bit like this.
USB MIDI interface
They consist of a USB plug for the computer, two MIDI plugs for the instrument, and a box in the middle of the cable containing the hardware.
Get the latest drivers from your manufacturer and follow their instructions for installation. For some interfaces this is just a matter of plugging in the USB and letting your computer automatically recognise it.
Next, plug the interface into your instrument. Make sure that all the ‘ins’ and ‘outs’ are connected properly. MIDI is a two way street, each device will send data out of its ‘MIDI OUT’ and listen for data on its ‘MIDI IN’.
Think of it as a river-like flow of data. Connect the MIDI OUT of your instrument to the MIDI IN of your computer and the MIDI OUT of the computer to the MIDI IN of the instrument.
Load the Xtractor of your choice. It'll look like this, or similar if you chose something other than guitar.
Click the button in the bottom right, as marked on the picture. You will now have an expanded Xtractor.
Now right down at the bottom is "Your performance" and a little volume meter. Play your instrument and if everything is working the bar graph will light up.
You might not hear what you play though. Click the setup button and select where Xtractor should send its MIDI output.
You should usually select the interface that you have plugged the instrument into so that the backing band goes back to the instrument and plays with its voices.
Go to the first lesson on the website. Read through the notes carefully. If you wish to, you can listen to the notes by clicking the play button next to each paragraph.
Sooner or later you will come to a practice session such as this one.
We recommend you watch the video first, you will then see and hear exactly what it is you will be doing.
Once you have watched the video, click the Xtractor button. Your browser will download a small file and open Xtractor. Click play in Xtractor and play along.
When you are happy with your performance and want to know how well you are doing then move on to recording (if you have a MIDI enabled instrument connected to your computer).
Click the record button in Xtractor and play the exercise.
When you are finished, click the Analyser button This graphical analysis will show:
- Top line: What you should have played.
- Bottom line: What you did play (with coloured feedback for how well you did).
At the bottom of the analysis is your total percentage score.
Close Analyser, rewind Xtractor, hit record and try again. Practise to improve on the points highlighted by the analysis.
When you are done – analyse again.
Repeat this process to improve your performance. When you are happy with your result you can save it for evidence and move onto the next part of the lesson.
