Plogue Chipsounds works great with its presets. But if you really want to nail the classic sounds you’re gonna need to dig into the rather confusing Wavetable. It’s really not as bad as it seems at first glance. This tutorial will help you learn how to use it to create classic sounds and also show you some great examples along the way.
Wave Sequencer Settings
Sync – This determines if the steps that happen in your wave table are in time with your MIDI tempo or the tempo specified in the BPM.
BPM – Set’s the internal BPM of the controller. It can be overridden by clicking Sync.
Vel – Check this if you want the notes playing to respond to the velocity (how hard you hit it) of your keyboard or midi notes. If you uncheck this, notes play at full volume. Usually you want to uncheck this for realistic NES sounds.
Loop start – Once the entire wave table plays through, this tells it where to start looping (if at all).
Rel Start – If you don’t want to start at the first command the first time through, put the step value in here that you wish to start on.
We will cover Sequence settings in a future tutorial.
Let’s start by looking at what each feature is for and the options under each one.
T – The T column is for tempo. This controls the length of each sequence of commands and notes that you play. For example, if you make two wave table items with T = ¼, when you play the note, the commands will execute starting from when the midi event (or keyboard hit) is detected and then the second command will kick of ¼ of a note later. Check the Sync checkbox to have it get it’s tempo from the MIDI environment (aka your song’s tempo). You can also put T=0 which means you want to change something about the upcoming note but not actually have it count time for this command. We’ll see how this works in the examples later on.
Type – The type column explains what each step will actually do. They are defined of the following:
- Null – Nothing happens, use this to leave a gap or a delay of a certain time before the next command executes.
- CC – Control Channel – You use this to change things like the vibrato, expression (volume level), filter cutoff ect.
- NoteOn / NoteOff – These do what you’d think, they tell the note to play or not to play. You can use this to make gaps, echoes and arpeggios.
- Pitch – This will take the note up or down the amount you specify in the Evt1 column. It is used for making arpeggios.
- KS – Keyswitch controls which of the channels of the default chip you are using, you use this to change from pulse1 to pulse2 to triangle, to noise. This can create some interesting effects that would be hard to do in a real tracker but not impossible for the chip to play.
Evt1 Column – The settings here depend on the type you’ve selected. For CC it’s the selection of the note property you wish to change. It will give you a drop-down of valid choices based on your type. For pitch, it is the amount of up or down steps you wish to go.
Evt2 Column – This column is usually the value of the change For example, if you select Type CC and Evt1 = 1 (which is Pitch LFO Depth aka Vibrato) Evt2 tells the system how much vibrato you want to be added to the note at this point.
Some examples will explain it best. We will explain what happens at each step in the process.
0 – The note plays for 1/64 of a whole note.
1 – The note is turned off for 1/48th of a whole note.
2 – The note is turned back on but at a lower volume (evt2=61)
3 – The note it turned off again.
4 – The note is turned on again at a much lower volume (evt2=20)
The 64th and 48th notes give it the offbeat echo effect that we commonly hear in music.
Looping Staccato Arpeggio
0 – The note is turned on and plays for 1/64th.
1 – The note is muted for 1/64th.
2 – The pitch is stepped up 5 half-steps. Since T=0, this is done before the next note plays.
3 – The next 5 half-step higher note plays for 1/64th.
4 – The note is turned off for 1/64th.
5 – The pitch is changed to +12, since T=0 it’s done before the next note plays (no time passes)
6 – The note is played an octave above the original for 1/64th.
7 – the note is muted again.
Loop start = 2 – the sequence goes back to step 2 until the user lets go of the keyboard or the MIDI note ends.
0 – The volume (CC=11) is set to 127 (evt2=127)
1 – The vibrato (CC=1) is set to 0. No time has passed, nor has a note played.
2 – The note begins to play for ¼, each time a key is pressed, steps 0 and 1 execute with no time pass before this step.
3,4,5 – After 1/8 the vibrato (CC=11) is increased slightly.
6 – The volume (CC=11) is decreased slightly.
7 – The vibrato reaches its maximum of 8 here.
Make sense? It’s really about setting up a series of steps that happen in a finite space of time. Do it right and you can really get some sweet sounds of out this unit.
