I want make sound effects but I can't read English for example, SND, ENV, LFO,and so on.
I can't understand what they representing.
Please tell me

What language is most proficient for you?

MeNTeN 2021-03-26 11:36

It's easier to use the Sound Composer to create sounds (maybe you are trying this alrady). You have all the options there and you can directly try them.

SND = Sound

WAV = Wave
TRI = Triangle
PUL = Pulse
NOI = Noise
SAW = Saw
PW = Pulse Width
LEN = Length

ENV = Envelope

ATT = Attack
DEC = Decay
SUS = Sustain
REL = Release

LFO = Low Frequency Oscillator

RAT = Rate
FRQ = Frequency
VOL = Volume
PW = Pulse Width

WAV = Wave
TRI = Triangle
SAW = Saw
SQR = Square
RND = Random
INV = Invert
ENV = Envelope
TRG = Trigger

It's hard to explain all of them, but it uses synth standards and you can find info on the internet.

Try translating this link too:

The intro has a phrase in it. The phrase is a good overview of the capabilities of LowRes NX:

"the sound most commonly associated with the technique is that of analog synthesizers of the 1960s and 1970s, in which the harmonics of simple waveforms such as sawtooth, pulse or square waves are attenuated with a voltage-controlled resonant low-pass filter."

Thank you both! I'm going to try it , but It looks difficult :(

The best is to experiment and listen how it sounds. Anyway, I have an idea for a little video, I will make one probably tomorrow :)

I encourage you to experiment with Sound Composer and create new SOUNDS, it is the button left of the FILE button... play with different settings unti you get something you like...

But, i would add one more step... TEST the sound in code... my experience is that you get slightly different sounds when you actually play them in code... so try

PLAY 0,10,1 SOUND 0
PLAY 0,50,1 SOUND 0
PLAY 0,90,1 SOUND 0

Then try

PLAY 0,50,1 SOUND 0
PLAY 0,50,5 SOUND 0
PLAY 0,50,20 SOUND 0

Also try

PLAY 0,40,1 SOUND 0
PLAY 0,41,1 SOUND 0
PLAY 0,42,1 SOUND 0


PLAY 0,50,1 SOUND 0
PLAY 1,51,1 SOUND 0
PLAY 2,52,1 SOUND 0
PLAY 3,53,1 SOUND 0

To experiment...

Each of these creates slightly different sounds, depending on your settings you made in Sound Composer

... you can also create a fancy sequence of sounds in TRACK, but i would start out learning how to edit SOUNDS first ;)

In the sound composer you have 3 tabs: patterns, tracks and sounds.

In the sounds tab: The first 3 buttons in the upper left corner are:

In the second row you can select the current sound. The numbers are in hexadecimal: 0 to 9 are the regular numbers, a=10, b=11, c=12, d=13, e=14, f=15.

In row SND:

In row ENV (envelope): the options in this row specify how the volume of the sound changes while playing. Sounds in lowres-nx are played in 4 stages:

LFO (low frequency oscillator): the LFO periodicaly changes the frequency, volume and pulse width of the sound.

In the bottom row you have the 2 OCT buttons to change the octave, then the music keyboard where you can test your sound. The STO and DEL buttons are inactive (they are only used in the track and pattern tabs).

everybody, Thank you very much… .you are so kind! :)

I have a question!
Here's example…
PLAY 0,50,1 SOUND 0
I can't understand these different between PLAY's first figure "0" and SOUND's "0"

Sorry for my poor English :(
I hope you can understand what I'm trying to say.

The first 0 is the voice number. LowRes NX has 4 voices (0-3), which means it can play 4 sounds at the same time. For example, if you play one sound on voice 0 and then another sound on voice 0, the first will stop.

For example you could have a simple music using voices 0 and 1, then you have still two more free voices for sound effects you can play at the same time.

The SOUND number is the "instrument" to play. It can be one of the 16 instruments you can create in Sound Composer.

LowRes NX has 4 channels for playing audio, numbered from 0 to 3. The first 0 selects channel 0. The channel number is only important if you want to play 2 or more sounds at the same time. The next example plays 2 sounds at the same time, the first on channel 0, the second on channel 1:
PLAY 0,50
PLAY 1,40

You have 16 different sound presets, you can edit them in the sound composer's sounds tab. SOUNDS's 0 selects sound preset 0. Here you can use a number from 0 to 15. First you need to go to sound composer, file, save, otherwise you won't hear any sound.
