Anyway - then Spectrum48 has the same sound-abilities what Spectrum128, Amstrad CPC, Atari ST or MSX have (they use the same chip standard: AY/YM). It means 4-bit sound, 3 channels + white noise generator, square wave and several 'buzzers'. Or - instead of it - I can use 3 channels of 4-bit digital sound with the AY, but then I have to fit all samples in 48Kb of RAM. :)

In case of chip-music, as "standard capabilities" I understand AY/YM working in 50hz (Atari ST can use this chip with 200hz of speed which gives the Atarians better audio effects due to their more powerful CPU - 16-bit, 8MHz. Cry cry!!).
So that's my weapon of choice: ZX Spectrum 48K with AY-interface.

For making chiptunes I use ZX Spectrum's Sound-Tracker 1.1 and for digital MOD-like music I use SampleTracker 2.0 and 2.1.

In 1994 I started to make music also for Amiga 500 (MOD / MED files) on OctaMED, but they were 4 channels traxx mostly - in 99%. :) We made only several 8 channels tracks on OctaMED but it was pretty hard task for old good A500, so usually I stick with 4ch. :)

In 2002 I founded AY-RIDERS band. We play chiptunes on our Spectrums (48K, 128K and higher models). AY-RIDERS' music can be found here: ay-riders.speccy.cz/ (My own music You can find here: yerzmyey.i-demo.pl/ ).

Some time later I started to make more music for Atari ST and STe (mostly digital, but also some chiptunes).
That's how the YM-DIGITAL band appeared in 2010: ym-digital.i-demo.pl/ - there are 2 albums for all enthusiasts of ym2149 chip and digital oldschool music.

In 2012 I bought an Amiga 1200 and was able to start making full 8-channels digital songs for the platform (with independent volumes). That's how the "RetroBeat" album appeared, for all fans of Amiga, and also for fans of retro-computer-music.

From time to time I make songs for Atari Falcon 030 (10 channels of digital music, on DHS-Tracker).

In 2015 I bought a British microcomputer Raspberry Pi 2 (smaller than the human hand-palm :) ), and I make some music on it, too.

So, in short, my software/hardware usually are:
SoundTracker on ZX81;
E-Tracker on SAM Coupe computer (Spectrum Advanced Machine);
MusicMon on ATARI 520ST;
DigiComposer on ATARI 520ST;
ProTracker on ATARI 520 ST;
Hex-Tracker on ATARI 520ST;
Octalyser on ATARI 1040 STE;
OctaMED on AMIGA 500;
DigiBooster on AMIGA 1200;
Digital Home Studio (DHS-Tracker) on ATARI Falcon 030
MilkyTracker on Raspberry Pi
