BREADAMP - The amazing C64 Sample player!

posted Aug 18, 2019, 11:49 AM by andi6510 The FPGASID Project   [ updated Aug 18, 2019, 11:49 AM ]

Here is something I want to share with you:

BREADAMP is a C64 sample player that comes with full featured functionality. It can play various (proprietary) sample formats directly from a REU compatible RAM expansion such as the 1541 Ultimate or the Turbo Cameleon.

Only a few weeks ago daddlertl from the Forum64 (german) started to work on BREADAMP. An even though the development is still ongoing, BREADAMP is already showing amazing performance!

And the best of all: BREADAMP has native support for the FPGASID!

With an FPGASID in you C64, BREADAMP plays  samples in stereo with less sampling noise than an original SID can do. And whilst original SIDs can play only those files that are created especially for them, FPGASID can play all files in best sound quality.

This video shows a short demo of the current BREADAMP version v03:

Of course it is possible to use you own music for playback. The audio files simply have to get converted to the correct format by a special tool and then packed into a REU file to load them into the memory expansion.

New Firmware release

posted Feb 24, 2019, 8:25 AM by andi6510 The FPGASID Project   [ updated Feb 24, 2019, 8:25 AM ]

Today I release a new firmware revision 0.A for the FPGASID:

Main changes:
  • New 6581 bias setting range and curve. Per default the bias is now tuned to a brighter sound which is the most audible difference to revision 09.
  • Some further improvements on the 6581 filters.
New Features:
  • LEDs can be switched off now.
  • The outputs can be switched to a mix of both SIDs allowing mono setups with a single speaker.
  • The firmware flashing procedure has been improved to increase the success rate.
  • FPGASID is now compatible to the EasyFlash 3 module.

FPGASID cable assembly

Hooray! Finally (after some failing attempts) our cable provider managed to make the correct cable assemblies for us.

We have approved them and production has started. Lead time will be a few weeks, though.

The breakout cable is a beauty! Click on the picture to see it in full detail.

New Audio Recordings with the FPGASID

posted Oct 22, 2018, 12:43 PM by andi6510 The FPGASID Project

The user SID Spieler known from the forum64.de has made some excelent recordings of well known (and not so well known) SID tunes. All of them are played back on a FPGASID in 6581 mode.

Please click here to enjoy these recordings.

In case you like the tunes don't forget to give SID Spieler a hug (e.g. virtually in the Forum64 link above).

Lecture about FPGASID

posted Oct 22, 2018, 12:13 PM by andi6510 The FPGASID Project   [ updated Nov 12, 2018, 1:23 PM ]

In September I held a lecture about the FPGASID Project at the DoReCo Party and at the Classic Computing 2018. I presented a historical step through the project with the main ups and downs and I gave a sound demo to the audience.

In case you can understand German you might want to have a look here:

Freud und Leid der FPGASID Entwicklung


The presentation material is available here.
The SID Files played in the Demo can be found (as executables) in this Disk image here.


FPGASID first production lot

posted Oct 21, 2018, 2:51 AM by andi6510 The FPGASID Project

Before we come to the bad news, let's have a look at the good news:

A week ago we have received the first production lot of FPGASIDs from our manufacturer! All devices are working fine and wait for their shipment!
FPGASID production devices

But, the bad news is that we cannot ship the devices without the accessory cables that are required for proper operation. And we are still waiting for those cables...

The samples we received from the cable manufacturer were not usable due to a couple of issues. So we had to go into another loop with the manufacturer... . With some luck we can get the cables in November.

Of course, we will start shipping immediately once we have everything in place.

The regular market introduction price will now be 74,95€. This is slightly more than promised due to some unforeseen cost. Sorry for this.
