ğ CellSynth defaults to using MIDI channel 1. If you want to change this use the above dialog.
From the Options menu choose Choose MIDI Input in the MIDI submenu.
This will display the OMS input selector dialog. Use this to choose your MIDI source as you would in any other OMS application.
Drag an Envelope Cell onto the Matrix next to the Sine Cell.
You have already enabled MIDI note on/off control on the Sine Cell. This means that the MIDI note from your keyboard (sequencer or whatever) is controlling the frequency of the Sine Cell, adjusting the frequency as you play different notes.
By enabling MIDI Note on / off on the Envelope Cell, it means that the note off information is controlling the Envelope Cell so that the note is released when the key is released. This is, of course, how most MIDI controllable synths operate.
You can adjust the envelope parameters manually using the ADSR edit window: If you leave both Cell's unmuted, you will not hear the effect of the envelope because you will still be hearing the output of the Sine Cell before it has passed through the envelope. If you mute the Sine Cell (press the mute button in the cell edit dialog or command-click cell in Matrix window) you will only hear the output of the Envelope Cell.
ğ Recap - this is an important point to remember and should be taken into account when designing any sound. If you donıt want to hear the original sound source but just the treated sound, remember to mute the Cell providing the sound source or it will still be going into the mix and heard at output.
Cells turn grey when muted.
Testing the Sound Using a MIDI Keyboard
To play from a MIDI keyboard (or any MIDI controller) make sure you have chosen your MIDI input in the OMS dialog accessed from the MIDI submenu item "Choose MIDI input" (as described earlier), and that the Controller is set to output on the same MIDI channel.
CellSynth must be active (click the speaker icon on the Matrix window or press spacebar) before it will receive MIDI from an external controller.
The tempo of the internal Clock can be set from the "Set Sync Tempo" dialog accessed from the "Options" menu.
CellSynth can, alternatively, be Syncıed to MIDI Clock from an external source, such as a Sequencer or any MIDI device that can output MIDI clock. This way CellSynth can be used as part of a larger MIDI setup.
To Sync CellSynth to an external Clock, select "Sync to MIDI Clock" from the "MIDI" submenu on "Options" menu.
CellSynth will immediately become active (you will see the Red LED glow), waiting for the MIDI Clock to start.
As soon as CellSynth receives Song Start or Continue, it will start playing in time with the External Clock.
There are a number of shortcuts to help sync samples, envelopes and delay lengths to tempo (if sync'ed to external clock set the internal clock to the same tempo):
Command-Click in a sample frequency dial to fit to tempo. Command-Click in a delay dial to fit delay to tempo. Command-Click in an envelope dial to fit A, D, S or R to tempo. Now use Control-Click to divide by 2 and Option-Click to multiply by 2 to adjust the value to the required multiple if necessary.
These two parameters are used to assign which Controller will control the Cell and what kind of range it will have. You can Command - Click the Controller LCD to set it to the last Controller received.
You can also assign a value to any Slider. This means that in actual fact, any parameter can be controlled via MIDI. However, this is a low priority function in CellSynth and if your Matrix is hitting your processor hard, you may notice a lag between the adjustment and the response from the Slider.
You can, in fact, assign the same controller in both the Cell Edit dialog and the Slider as we are going to do in this next example, and then you will get a good response and still be able to see the sliders move on-screen.
First you need a MIDI device with several Sliders or knobs which you can assign Control Numbers to. There are many such devices on the market, and many synths now have a generous number of assignable controls.
Make sure your MIDI device is transmitting on the same channel that CellSynth is set to receive (Options-MIDI-Set MIDI channel) and that the MIDI input the MIDI device will be transmitting to has been selected in the "Choose MIDI input" dialog (Options-MIDI-Choose MIDI input).
A good example of a Matrix that has been setup to use with an external MIDI device is "Sample 5 Loop Mixing and Playing" in the Matrix Files folder (and accessible from the pop-up menu at the top of the Matrix window (under Basic Examples 2). This Matrix has been setup to use MIDI controllers 2 to 6. The Control Numbers are optionally displayed (Options menu: MIDI: Show Controller Names) on each Cell in the Matrix Window. You will also notice that five tear off Sliders have been setup for easy access.
You can either assign a control value to a parameter in the Cell Edit dialog or, if you plan to use Sliders, it can be done from the Slider itself. See the explanation of the Pro's and Con's earlier in this chapter.
To assign a value in the Cell Edit dialog automatically, move the knob or slider on your MIDI device and then command-click on the Controller Parameterıs dial or numeric display and the value received will be set. You can also set this by simply typing in the value or turning the dial until the correct value is displayed. Adjust the Control Amount to give a suitable range.
To create a Slider (which can be used independently of the Cell Edit window and also gives a visual reference of the Parameterıs value) click in the Parameter's LCD display and drag:
In this example the Sliders are controlling the Gain Parameter of the Sample Cells. Because this is the main MIDI controlled parameter on Sample Cells, and we have already assigned a Controller in the Cell Edit dialog, it is not necessary to set one here. However, in order to see the Slider move on-screen, we can still assign a MIDI Controller to the Slider as well.
Simply move the control on your MIDI device that you wish to use and command-click on the Slider. A dialog will appear with the value CellSynth received from your MIDI device as its default. You can also set the control range from this dialog:
Try experimenting with the Sample 5 Matrix example. Assign some controllers to the Sliders from your own MIDI device.
The Event Sequencer is covered elsewhere in this manual but lets remind ourselves that we can use the Event Sequencer to automate or arrange sequences of events using MIDI controllers. Any Cell can be controlled using MIDI controllers and therefore the possibilities are endless. You could automate filter sweeps, volume changes, delay length, pan and so on.
By assigning Controllers to Sliders, any parameter can be controlled, but it should be remembered that MIDI control over Sliders has a low priority in CellSynth. For smooth response try and use the Cellıs main parameter assigned in the Cell Edit dialog.
ğ Here are the Cellsı Main Controllable Parameters: Sine gain (also known as volume!) Square gain Sawtooth gain Triangle gain Noise gain Samples gain Filters frequency Mixer gain Panner pan amount Black Box gain Delay delay length Envelope gain Reverb gain Sequencer none
To set the Keyspan of a Cell, open the Cell Edit window and Option-Click on the MIDI Note on/off button.
This will open the Cellıs Keyspan window:
To set the Keyspan, either type in the note numbers manually or click on the note at either end of the current keyspan and drag with the mouse.
It also means that you could control them from the Event Sequencer, which you could then use to arrange drum parts. Each cell that has MIDI Note on/off activated will receive the output from the Event Sequencer, so this is one Cell that can be placed anywhere on the Matrix and does not need to be connected to the other Cells on the Matrix.
