Hello, I've been playing around with the new sound feature a bit more, and I've noticed that there's a difference from how sound works on RISC OS. On RISC OS it's possible to play a sound which is completely silent by using 0 as the volume parameter for the SOUND command. This can be useful for cutt...

Sorry if this question is already answered. Is it possible to check whether there's something in the keyboard buffer in Matrix Brandy? I notice that ADVAL(-1) always returns 0.

Sorry, I see now that I was wrong about the lowest note available being a# (pitch number 0). I actually wasn't aware of the finer control that's allowed by specifiying numbers between 256 and 32767. Now that I know about that I'll be using it. At the same time, I still think the feature that lets yo...

I actually discovered it by accident... If it's undocumented it shouldn't be used (or emulated), in my opinion. There's nothing to say that it's safe to use or that it will work reliably. I understand and respect your opinion, but I disagree. It's a very useful feature. It seems to be impossible to...

A useful feature of SOUND that RISC OS has is that you can supply a negative number as the pitch parameter in order to play a sound at a specific frequency in hz. FWIW, that feature seems not to be documented here so maybe it was a late addition. Ah that's Interesting. I actually discovered it by a...

I'm really glad to see that sound support has been added, big thanks to you and David H for this. A useful feature of SOUND that RISC OS has is that you can supply a negative number as the pitch parameter in order to play a sound at a specific frequency in hz. I tested it with a short program and I ...

It's been a long time coming, but I've just checked in a commit that implements AUTO. Thanks very much for this! By the way, tonight I've come across something that's surprised me and I don't know if it's a bug in brandy, or if I'm just doing something very wrong. I was bored and I wrote a silly pr...

Maybe so, but don't forget that *EXEC is useful for stuff like pre-filling the INPUT buffer.

I just compiled the latest version of brandy and unlike previous versions (and unlike the original brandy) it immediately closes after the program ends if you run it with a program file as a command line argument. Previously it only did that if you specified -quit. Is this intentional? If it is inte...

and many people (certainly within the RISC OS community) consider me to be something of a traitor and to be 'anti Acorn'

If this is true, those people are just being silly and you shouldn't be concerned about what they think.

Thanks Richard.

That's our man Richard. This sound recorder app is great!

I don't have anything important to say, but I just wanted to say again, big thanks for all your work on Matrix Brandy. I use it a lot and I'm really glad that it's being maintained.

It's not closely related to the current discussion, but I'm wondering, is there any chance that matrix brandy would be ported to SDL2 at some point in the future? I'm thinking that problems like this would be less likely to happen with SDL2. Using SDL2 might also make it easier to implement features...

I'm glad to hear this. Thanks, Richard.

I think Richard is right. From my perspective as an end user of brandy, the behaviour of BGET#, EOF#, etc, might as well be considered a part of (brandy) BASIC.

Thanks. EOF#0 now causes an error as it should. But I've also just noticed now that BPUT#0 and BGET#0 have the same problem - BPUT#0 doesn't cause an error and BGET#0 returns 0 without causing an error. (I should have tested those before I posted about the EOF#0 problem, sorry about that)

Hello,

I've just discovered a bug with EOF#. EOF#0 returns 0, instead of causing an "invalid channel" error as it does in other versions of BBC BASIC.

I'm a bit late to this thread, but, I usually write my programs using my favourite text editor "Mousepad", save as text, and load into Brandy either by passing the program text file as a command line argument or with CHAIN. When I want to write a program for the BBC Micro or RISC OS, I often start w...

Thanks sweh! I've tested this and it works.

Maybe it's not related, but I recently wrote a resampler for Matrix Brandy BASIC. It would probably not be much work to extend it into something that could be used to make music.

Try an extra leading slash. (*/ is the same as *RUN I think.)

Thanks, that worked. I've also just worked out that "$PWD/binfile" works for executing something that's in the current working directory.

Hello again, I've noticed two issues (or maybe three issues, with two of them similar but separate) related to OSCLI. I found myself in the situation where I wanted to use OSCLI to run an executable in the current directory. So I tried OSCLI "./binfile" But this didn't work because any command strin...

Has there been any progress towards sound support? I think jgharston said he was looking into it, or maybe I'm remembering wrongly.

Merry Christmas, McDougall!

Hi, And yes I have to coding in other languages, but I just find them a lot more I don't know less friendly. What I love about retro machines is this naivety they approach life with and I think I relate to that lol :lol: If you prefer BASIC, you can still use it on modern computers. If you haven't t...

Hi Pablos, Do you, or have you done, any programming on modern computers/laptops/etc? I'm just wondering because from reading your post, I get the impression that you've felt a bit daunted by the experience of trying to create stuff on the BBC Micro, trying to fit everything in the small memory and ...

Just a small aside, I've pressed a text-mode build into service running a program to process DHCP logs into a MySQL database at work. My first log-mangler (to reshape the data into INSERT statements) was a bash script, and processed about 30% of the 400MB log file overnight, after which point I gav...

That is something I would like to do - but it's so far away from anything I've done before (I've never done sound programming previously) I will be struggling to make it work. I was thinking even leaning towards the BBC Micro style, as it might be simpler than having to implement sample files (like...

With debian or ubuntu, I think all you would need to do to be able to compile matrix brandy is "sudo apt-get install build-essential libsdl1.2-dev". (I might be forgetting other dependencies) Puppy Linux seems to be a bit strange, compared to other linux distros. I would never have expected that ins...
