BOL PROCESSOR is a pro­gram ini­ti­at­ed by Bernard Bel for music com­po­si­tion and impro­vi­sa­tion with real-time MIDI, MIDI file, Csound, and text out­put options. The ear­li­est imple­men­ta­tion of Bol Processor (BP1) on an Apple II in 1981, was an expert sys­tem used by Jim Kippen to mod­el the impro­vi­sa­tion­al process­es of tabla play­ers in North India — see arti­cle (1992) and inter­view (2021).

The Bol Processor pro­duces music with a set of rules (a com­po­si­tion­al gram­mar) and/or text scores that can be typed in, cap­tured from a MIDI instru­ment or import­ed from MusicXML scores. These rule sets are sim­i­lar to for­mal gram­mars (context-free, context-sensitive, etc.) used in com­put­er sci­ence to define machine-readable languages.

When impro­vis­ing, sets of eli­gi­ble rules can be super­vised by rule weights (e.g. Mozart’s musi­cal dice game and Interactive impro­vi­sa­tion) and/or/ by numerical/logical flags — e.g. Computing ‘ideas’:

Computing ‘ideas’: numeric/logic flags in Carnatic musi­cal style (Srikumar K. Subramanian, 1995)

As a com­po­si­tion­al tool, the Bol Processor (BP2) has been suc­cess­ful in mod­el­ling music of many styles, includ­ing Western clas­si­cal music, ser­i­al music, con­tem­po­rary art music includ­ing min­i­mal­ism, and Indian clas­si­cal music. After the imple­men­ta­tion of its Csound inter­face, BP2 won the 1997 Bourges International Prize (ex aequo with Cecilia) in the cat­e­go­ry of computer-aided com­po­si­tion and real­i­sa­tion software.

A gram­mar cre­at­ing a poly­met­ric struc­ture along with sound-object and piano-roll dis­plays (more details)

One of the great fea­tures of the Bol Processor is its abil­i­ty to rep­re­sent com­plex time struc­tures using a poly­met­ric mod­el that is acces­si­ble to (human) com­posers, but at a lev­el of abstrac­tion that encom­pass­es a wide vari­ety of musi­cal gen­res — lis­ten to exam­ples below!

For exam­ple, embed­ded poly­met­ric struc­tures can cre­ate ruba­to or nat­u­ral­ly flow­ing move­ments with­out the need for speed con­trol instruc­tions, as shown in Harm Visser’s “Waves”:

Bol Processor representation of time-objects belonging to a polymetric structure, with symbolic and physical time frameworks.
Time-objects arranged along sym­bol­ic and phys­i­cal time

The final prod­uct of a Bol Processor gram­mar is a struc­ture of time objects. These time objects are resized and locat­ed in phys­i­cal time by a time-setting algo­rithm.

Timing a poly­met­ric struc­ture amounts to solv­ing a sys­tem of con­straints depend­ing on (1) the met­ric and topo­log­i­cal prop­er­ties of the time objects, (2) the con­texts in which they are found, and (3) para­me­ters relat­ed to the per­for­mance itself: “smooth” or “stri­at­ed” time, tem­po, etc. Input time objects can also be used to syn­chro­nise events or to mod­i­fy para­me­ters in gen­er­a­tive grammars.

The the­o­ret­i­cal frame­work of poly­met­ric struc­tures has been a source of inspi­ra­tion for the devel­op­ment of oth­er music com­po­si­tion soft­ware, such as TidleCycles (see Alan Blackwell et al. Live Coding: A User’s Manual, MIT 2022, page 195).

In the cur­rent imple­men­ta­tion of the Bol Processor, time-objects are instan­ti­at­ed as sound-objects: sequences of MIDI out/in mes­sages or Csound instruc­tions. This mod­el could eas­i­ly be applied to oth­er types of events, such as the sched­ul­ing, siz­ing and pre­cise tim­ing of video clips, robot com­mands etc.

Bol Processor BP2 began as a share­ware appli­ca­tion for Macintosh com­put­ers devel­oped by Bernard Bel with the help of Srikumar Karaikudi Subramanian. In the spring of 2006,  Anthony Kozar joined the project and open-sourced the pro­gram in the hope that a com­mu­ni­ty of devel­op­ers would come togeth­er to port it to oth­er plat­forms and fur­ther enhance its music-making capa­bil­i­ties. The port­ing BP2 to Mac OS X was com­plet­ed by Anthony Kozar in June 2007.

A multi-platform ver­sion (BP3) was imple­ment­ed in 2020. The core engine of Bol Processor BP3 is a con­sole appli­ca­tion that runs on MacOS, Linux and Windows (on both 32-bit and 64-bit Intel proces­sors). It is cur­rent­ly con­trolled via a PHP inter­face, which we intend to com­pile as a stand­alone appli­ca­tion.

Transposition of the Ma-grama basic scale in Indian music

Bol Processor BP3 intro­duced new fea­tures due to its close asso­ci­a­tion with Csound. Essential areas of musi­col­o­gy rel­e­vant to com­put­er music are cov­ered on this site, includ­ing the issue of micro­tonal­i­ty applied to just into­na­tion in Western har­mo­ny, tem­pera­ment in European baroque music, and raga into­na­tion in Hindustani or Carnatic music.

A major achieve­ment of recent work has been the import of MusicXML scores into Western music nota­tion, paving the way for the reuse of frag­ments of musi­cal works in BP3’s gen­er­a­tive sys­tem. The fol­low­ing record­ings are com­plete musi­cal works, each of which accu­rate­ly encod­ed as a sin­gle poly­met­ric expres­sion:

J.S. Bach's 1st Prelude matched by Bol Processor against Kirnberger III temperament
Matching J.S. Bach’s 1st Prelude in C major
with Kirnberger III tem­pera­ment
(More details)

This site con­tains a doc­u­men­ta­tion of the algo­rithms imple­ment­ed in the Bol Processor, as well as tuto­ri­als for a bet­ter under­stand­ing of relat­ed con­cepts in dif­fer­ent musi­cal traditions.

Basic con­cepts are explained to read­ers unfa­mil­iar with these dif­fer­ent cultures.

As a project host­ed by a GitHub open-source repos­i­to­ry, we are tak­ing Bol Processor into the next stages of its evo­lu­tion.

We hope that BP3 will become more mod­u­lar, sep­a­rat­ing its com­pu­ta­tion­al engines for musi­cal gram­mars, poly­met­ric expres­sions, and pow­er­ful time-setting algo­rithms into soft­ware libraries that can be incor­po­rat­ed into oth­er open source software.

➡ Download and check Bol Processor ‘BP3’ with its PHP inter­face
➡ Join our project on GitHub!
➡ Read the BP3-to-do file

Please join the BP users help forum , the BP open dis­cus­sion forum and/or the BP devel­op­ers list to keep up to date with work the progress of the work and to dis­cuss relat­ed the­o­ret­i­cal issues.

A stand­alone ver­sion com­piled from the PHP/Javascript/C pack­age is about to be released. We plan to use the PHP Desktop plat­form. We need the help of programmer(s) con­ver­sant with this envi­ron­ment!

➡ Download a PowerPoint slideshow intro­duc­ing the Bol Processor with sound exam­ples (zip file, 150 Mb)
➡ YouTube video: “Bol Processor - 39 years!”

Vintage ver­sions of BP2 are still avail­able for both Mac OS X and Mac OS 7-9

At the cur­rent state of the art, the Bol Processor has reached a high lev­el of the­o­ret­i­cal research into time and tonal struc­tures. This project is open to engi­neers who wish to devel­op com­mer­cial prod­ucts using (parts of) its algo­rithms. Collaboration with cor­po­rate actors should in turn pave the way for more sophis­ti­cat­ed musi­co­log­i­cal research, while (hope­ful­ly) mak­ing mon­ey from their inno­v­a­tive products…
