leelinn Posted January 5, 2008 Report Share Posted January 5, 2008 Hello,i'm considering to (finally) complete my midibox sid.I started building the old midibox SID v.1. but since the features of new version seem to be really interesting i've decided to upgrade my project to version 2.This is the stuff i have:2 MBHP_CORE v2 with 2 PIC18F452 burned with old JDM2 MBHP_SID v2 2 SID 65814x20 Blue LCDMBHP_DINX4MBHP_DOUTx4leds, 1 rotary encoder, buttons for minimum control surfaceoptimized PSU circuit (tnx to Pocketmaster from Swiss for building him for me) + C64 power supply2 x 24LC256 bankstickWhat do i need to upgrade to version 2?In particular it seems that now it's possible to connect 2 SIDs to 1 Core directly for STEREO purpose. Since i have 2 CORE modules, what is it best choice for me? to buy two new PICs for realizing a separeted multi SID device or going straight to the new STEREO feature?tnx a lot for big support!!!lee Quote Link to comment Share on other sites More sharing options...
TK. Posted January 5, 2008 Report Share Posted January 5, 2008 Hi Lee,see this page: http://www.ucapps.de/midibox_sid_manual_up.htmlThe stereo option is strongly recommented - you will love it! :)Not only that you can play stereo sounds, it also allows you to play two basslines per core, or 6 drum instruments the same time, or 6 voice polyphonic soundsBest Regards, Thorsten.

Smithy Posted January 6, 2008 Report Share Posted January 6, 2008 Thats a pretty modest part list for the upgrade in all fairness!TK.......YOU DA MAN!!! Quote Link to comment Share on other sites More sharing options...

This is obscure to me);1k resistor for the new LCD connection in 4bit mode (...yes..a i need to free 4 connections D0 to D4);1k resistor for CORE CAN connection;new 24LC512;1 1N4148 diode (or 2 assuming that even if in Stereo mode i need 2 COREs)Stereo mode and bassline: i've heard the samples. GREAT features!!(it's also nice the use of matrix screen as eq screen :))) )tnx a lot for help! Quote Link to comment Share on other sites More sharing options...
seppoman Posted January 6, 2008 Report Share Posted January 6, 2008 Hi,your list looks ok to me - don't know which 1k resistor you mean regarding the LCD?for stereo operation, you need only one core per two SIDs. Of course as you already have the second core module you could also consider adding another two SID modules to have two channels of stereo SID fun :)S Quote Link to comment Share on other sites More sharing options...

In the previous version you didn't need to put it ( i did so) 'cause you connected all the pins. Now you have to free pins from D0 to D3.
