Welcome to the 1-Bit Forum (aka The Introduction Thread) (Page 2 of 2)

Wow, excellent song! Not much of a Musical guy myself, but that's certainly some very solid work.

Very curious about that demo. Let us know if you need help with anything.

Hi uglifruit. Welcome to the forum

I've just listened to your musical. Wow some great work, particularly like 'I could be a paperboy' and 'in space'.

Also great to hear some 1-bit speccy music used in the 1st track

Hi, my name is Pedro Pimenta aka Jumperror, I come from Portugal and I joined this forum by recommendation of AtariTufty.
First I should say, I'm quite new to all this, at least compared to most (if not all) people I've met lately in the Speccy scene.
I was born in '92, so I heard about the Spectrum somewhat recently and only bought my first one about five years ago.

I've been making music for some time, all self-taught, and ended up making music for my first game in 2016.
Last year, I was challenged by a friend to start making music for the Speccy, so I started learning how to do it and slowly I got into my first game, then I joined the vibrant Spectrum game-making community and have been making music for several games, you can see most of what I've been doing here (in chronological order from the first to the most recent game):

In the beggining I used to work more with the beeper, but lately I've been making only AY music. Now, because Tufty introduced me to this great community, I've become more interested in getting back to the beeper and trying to make the most out of it.

Here you can see two of my ZX Spectrum Beeper works (and for some other platforms also):

I've also been trying recently to expand to other systems, already did some music for the MSX, Atari ST (see a demo here: https://www.youtube.com/watch?v=H3v5gTwRHeQ) and more recently Amstrad CPC, but what I love most are the more limited systems, I really enjoy challenges.

I'm glad I've found this community, I had no idea there where 1bit physical music releases, live sets and so many people doing great music, it's a pleasure to join you all.

Nice musics! Welcome here! Do you also have an account on Battle of the Bits?

First of all, thanks for the warm welcome!
I'm really happy to know you like what I've been doing.

Right now I just use Vortex Tracker and Beepola (also Arkos tracker lately), but while Vortex is an amazing program I feel like I could do more with the Beeper, because I think Beepola is quite limited.
Utz mentioned new beeper engines, so where should I look first to know more about that?
I don't know any others aside from the ones in Beepola, so I have to ask why doesn't beepola have more of these new engines and which trackers currently use them?

To answer to Garvalf, no I don't have an account there. Actually I never made any music for demos or competitions and because I'm usually busy making music for games I haven't made much music outside that lately.
But it looks interesting, will try and join later.

Tufty, thanks for telling me about this forum, I will be taking a look at Bintracker first, it seems easier to get into. 1tracker's interface is very minimal, reminds me of monotone. Honestly, looking at it, I don't even know where to start

Hey, party people!

I do a bit of dev work on the Laser 200 aka VZ200.. same as Bushy who has posted on here in the past.

Hope to do a few little tunes and see if I can get it playing on our platform. I know NOTHING about music so please don't expect too much haha!

Thanks for letting me into your world.

Hello, i have not much to offer. my own sound code it 4-bits for ay. Bit i like asm and z80 code and hope to learn here. I made 2 or 3 dis-assemblies from 1bit speech. there is a 'crosover' routine that uses ay for its 1bit speech , its called "ble-ble' i think.

Hi Utz, not perse 1bit sound but i try to make a spot in it.
but its more the thoughed.
with a 224 scanline procedure you could have a 1 bit sound sqeuch
with about 320 scanlines and 50  frames thats only about 16,000  BITS per second,equ 1,8 KB per second ??

Hi Utz
if i try to make one OUT (254) per scanline then that should give a hiss sound of about 1.5KB per second.

eg this is the start off the interrupt from Bordertron for 16k

Now i want to place that OUT 254 on the correct spot for a steady 224 tstate steprate. probably with an EXX. but, thats just the thought.

Hi there,

I'm Andy, based in the UK. I am an old school Sinclair fan, growing up with the work of Tim Follin, David Whittaker and Ben Daglish.

At the moment I'm designing a new Z80-based computer, with an 8Mhz processor and a 1-bit audio path. I'm trying to figure out the best audio routine to show it off, but still haven't quite got my head around converting for the different CPU speeds - the core frequencies aren't too bad, but when there are effects and tempo to consider as well, my head explodes!

I'll pop some details of the circuits in the other forum if people are interested - it has a simple one transistor amplifier and cellphone speaker so though it's not the loudest, it should be able to play some interesting music.

Welcome to the forum Andy. As utz says, not the busiest forum but we do check regularly and always great to see new members.
A mine of invaluable info is available here in relation to 1-bit sound and engines.
